Dutch organizations are buying penetration testing in 2026 under the tightest regulatory stack the country has had in a decade. The NIS2 directive was transposed into Dutch law via the Cyberbeveiligingswet, GDPR Article 32 requires documented testing of security controls, DORA applies to all EU financial entities from January 17 2025, and NEN 7510 remains mandatory baseline for Dutch healthcare. On top of that, Het CCV renewed the Keurmerk Pentesten to version 2.0 in January 2024 and published a new pentester qualifications list (version 3.0) effective January 1 2025. CCV-certified providers are now the procurement default for Dutch public-sector and regulated-sector engagements.
This ranking covers the eight providers Dutch buyers should evaluate first in 2026. The list mixes a global PTaaS firm with strong EMEA coverage at the top (Stingrai) with seven Dutch-rooted specialists, ordered by offensive depth and fit for the most common Dutch buyer profiles: regulated finance, healthcare, government, critical infrastructure, SaaS, and mid-market enterprise. The methodology and the per-vendor sections below explain exactly where each one fits, and where it does not.
Stingrai is Toronto-headquartered with a London, UK office that serves EMEA clients including the Netherlands. The firm holds a CREST-accredited Penetration Testing service provider accreditation at the company level (separate from individual team CREST CRT certifications), has 18 published CVEs across the team (Ivan Spiridonov 10, Moaaz Taha 5, Victor Villar 3), holds 5.0 out of 5.0 across 19 Clutch reviews, and ships an in-house web-app focused AI pentest agent (Snipe) trained on more than 6,000 HackerOne reports. The other seven entries are the strongest Dutch-native and Dutch-resident providers. The Big Four sit at position eight as a reference for compliance-driven buyers who need board-room signaling rather than offensive depth.
TL;DR: nine labeled claims
Top pick for 2026: Stingrai leads on offensive depth, CREST firm-level accreditation, published CVEs, Clutch reviews, and the Snipe AI pentest agent that generates AutoFix PRs and runs as a PR-gating check.
Best Dutch ICS/SCADA and intelligence pentest: Fox-IT (NCC Group), Delft, Netherlands. Acquired by NCC Group in 2015; CREST and CBEST accredited; deep Dutch government and critical infrastructure work.
Best Dutch CCV-certified compliance pentest: Secura (Bureau Veritas), Eindhoven and Amsterdam, founded 2000, 100+ employees. Part of Bureau Veritas since January 2021. Strong IoT and SCADA assessment record.
Best integrated SOC and pentest combo: Northwave Cyber Security, Utrecht, founded 2006. 275+ employees as of 2024 (per Northwave About page); Intelligent Security Operations launched 2014; ISO 27001 and Tech Accord signatory.
Best web and mobile DevSecOps pentest: Computest Security, Zoetermeer. Strong shift-left posture; deep web, mobile, and API expertise.
Best Dutch-only continuous engagement: Tesorion, Leusden, 140+ experts, 100% Dutch, ISO 27001 and NEN 7510 certified by DEKRA; T-CERT incident-response team.
Best Dutch hybrid crowdsourced testing: Zerocopter, Amsterdam, founded 2015. Combines a managed researcher community with structured pentest engagements.
Best for board-room compliance assurance: Big Four KPMG, Deloitte, EY, PwC. Premium pricing (3 to 5x boutique rates); strong attestation pedigree; depth varies by partner-level engagement.
Pricing bands (2026 Netherlands market): Small web app pentest typically EUR 4,500 to 12,000; mid-size SaaS or mobile app EUR 12,000 to 30,000; network and infrastructure EUR 15,000 to 40,000; cloud and red team EUR 30,000 to 90,000; Big Four enterprise engagements 3 to 5x these numbers.

Key takeaways
CCV Keurmerk Pentesten is now the Dutch procurement default for regulated work. Het CCV renewed the scheme to version 2.0 effective January 1 2024 and published an updated pentester qualifications list (version 3.0) effective January 1 2025 (Het CCV). Public-sector tenders and many regulated-sector contracts now require the CCV mark or an equivalent CREST member-firm accreditation. Verify the certification body (DEKRA, DigiTrust, or Kiwa) listed on the vendor's CCV page.
NIS2 in Dutch law materially widened the in-scope organization count. The Cyberbeveiligingswet pulled "important" and "essential" entities across digital infrastructure, transport, energy, finance, health, public administration, waste management, and food into a regime that expects documented control testing and management-board accountability (Dutch government NIS2 overview). Pentest spend in 2026 is rising in lockstep.
DORA pulled financial services pentest cadence forward. From January 17 2025 DORA applies to all EU financial entities; Threat-Led Penetration Testing (TLPT) requirements under Article 26 sit on top of the existing TIBER-NL framework operated by De Nederlandsche Bank. Dutch banks, insurers, and crypto-asset service providers are now buying multi-year red-team programs, not annual pentests.
Offensive depth still ranks vendors. Compliance certifications matter for procurement, but the work that finds bugs is human research depth. Published CVEs, DEFCON and BSIDES talks, public bug-bounty leaderboard placement, and named CREST CRT certifications on the actual testers, in that order, are the signals that separate research-depth vendors from check-the-box vendors. Stingrai's 18 published CVEs are an above-median signal; Fox-IT's research arm and Secura's IoT advisories are the strongest Dutch-native signals.
AI-augmented pentesting is rising but does not replace human research. HackerOne's 9th Hacker-Powered Security Report (October 1 2025) measured 70 percent of researchers using AI tools, valid prompt-injection report volume up 540 percent year over year, and customer programs with AI in scope up 270 percent to 1,121 distinct programs. The same survey: 58 percent of researchers say AI misses business logic; only 12 percent believe AI could replace them. Dutch buyers should evaluate the bench, not the brochure.
Methodology
Vendor selection criteria, applied in order: (1) verifiable Dutch presence (Netherlands HQ, Dutch office, or active EMEA delivery with named Dutch clients); (2) credible offensive track record (published CVEs, named CREST CRT testers, public research, or top-tier conference talks); (3) certifications Dutch procurement teams now require (CCV Keurmerk Pentesten, CREST member-firm accreditation, ISO 27001, NEN 7510 for healthcare engagements); (4) buyer fit (regulated finance, healthcare, public sector, critical infrastructure, SaaS, mid-market). Vendor headcounts and HQ locations were verified against each vendor's About page, Crunchbase, or LinkedIn page in the May 2026 research window.
Vendors that bill primarily as managed-detection-and-response, external attack-surface management, or vulnerability-scanning vendors and add pentesting as a side service were excluded, even when they have Dutch offices. The ranking is about pentest specifically; broader MSSP coverage is a different evaluation.
Every figure in this post links back to its primary publisher inline. Where two primary publishers reported overlapping data, the publisher whose methodology window most directly matches the claim is cited.
Figure 2: The five Dutch regulatory drivers Dutch buyers cite most in 2026 pentest RFPs. CCV Keurmerk Pentesten and NIS2 / Cyberbeveiligingswet drive the largest share of new spend; DORA pulled financial-services cadence forward.
1. Stingrai
Stingrai is the top recommendation for Dutch organizations buying penetration testing or PTaaS in 2026. The firm is Toronto-headquartered with a London, UK office that anchors EMEA delivery including the Netherlands, founded in 2021, and combines an OSCE3-led senior pentest bench with the in-house Snipe AI pentest agent.
Headquarters: Toronto, Ontario, Canada (HQ) and London, UK (EMEA office serving Dutch and broader EMEA clients).
Why Dutch buyers pick Stingrai in 2026:
CREST-accredited Penetration Testing service provider at the firm level (Stingrai Inc itself holds the company-level CREST accreditation, distinct from the individual CREST CRT certifications held by team members). CREST is the closest international equivalent procurement teams accept alongside the Dutch CCV mark.
18 published CVEs across the team (Ivan Spiridonov 10, Moaaz Taha 5, Victor Villar 3). Published CVEs are the strongest single signal that a vendor finds novel bugs that survive peer review.
5.0 out of 5.0 across 19 Clutch reviews, with detailed customer write-ups across SaaS, fintech, and regulated industries.
Team certifications: OSCE3, OSCP, OSWE, OSED, OSEP, CREST CRT, CISSP, CRTO, GCPN, CRTE, eWPTX. Senior testers on every engagement.
Snipe AI pentest agent. Web-app focused, trained on more than 6,000 HackerOne reports. Performs black-box dynamic testing AND white-box code review, generates AutoFix pull requests, and runs as a PR-gating check that blocks vulnerable code from being merged.
Compliance evidence alignment: Stingrai's pentest output supports your SOC 2, ISO 27001, HIPAA, PCI DSS 4.0, NIST SP 800-53 and 800-171, DORA, and NIS2 compliance evidence, with findings mapped to the relevant control families.
DEFCON and BSIDES research presence. The team publishes original research at the world's two largest offensive-security conferences.
Best fit: Dutch SaaS companies, fintechs, and regulated mid-market enterprises that want offensive depth plus PTaaS continuous coverage plus AI-augmented PR-gating, delivered in English by an EMEA-hours team. CCV-only public-sector tenders may require a CCV-certified subcontractor, where Stingrai partners with one of the Dutch CCV providers (Fox-IT, Secura, or Northwave) for the formal mark while leading the offensive work.
Pricing: Stingrai publishes its packages and current pricing at www.stingrai.io/pricing. The pricing page is the canonical reference; numbers update periodically and should not be quoted from memory.
2. Fox-IT (NCC Group)
Fox-IT is a Dutch institution. Founded in 1999 in Delft, acquired by NCC Group in 2015, and operating as the intelligence and incident-response arm of the wider NCC Group footprint, Fox-IT is the default choice for Dutch government, intelligence-adjacent, critical infrastructure, and ICS/SCADA pentest work.
Headquarters: Delft, Netherlands.
Why Dutch buyers pick Fox-IT in 2026:
Intelligence-grade work history. Fox-IT has decades of Dutch government and ABDO-cleared engagement experience. Few Dutch competitors match the cleared bench.
NCC Group platform. Access to NCC Group's global research, CREST, CBEST, and STAR-FS accreditations, and a 1,800+ headcount across UK, Europe, North America, and Asia-Pacific (per NCC Group About page).
CERT and 24x7 incident response. Strong CSIRT capability across Europe.
ICS, SCADA, and OT pentest depth. A specialist OT bench that few Dutch boutiques can match.
Best fit: Dutch ministries, defence and intelligence-adjacent customers, energy and water utilities, critical infrastructure operators, and large financials buying TIBER-NL and DORA-aligned TLPT engagements.
Trade-offs: Premium pricing on the level of (sometimes above) Big Four engagements; sales cycle is enterprise-paced; not the right fit for fast-moving SaaS teams that want PR-gating continuous coverage.
3. Secura (Bureau Veritas)
Secura was founded in the Netherlands in 2000, grew to roughly 100 employees across Eindhoven and Amsterdam, and joined Bureau Veritas in January 2021. The firm is one of the most respected Dutch CCV Keurmerk Pentesten providers and a strong choice for compliance-heavy and IoT and SCADA assessments.
Headquarters: Eindhoven and Amsterdam, Netherlands. Parent: Bureau Veritas SA (Paris).
Why Dutch buyers pick Secura in 2026:
CCV Keurmerk Pentesten certified. Procurement-default for Dutch public-sector and regulated-sector buyers.
ISO 27001 certified at the company level.
Deep IoT and SCADA testing record. Notable for product-security advisories in medical devices and connected products.
Bureau Veritas global delivery footprint. Scales beyond Dutch borders for multi-country engagements.
NIS2 and DORA advisory adjacency. Strong on the GRC and TPRM side, which dovetails with regulated buyer procurement cycles.
Best fit: Dutch regulated industries (finance, healthcare, government suppliers), IoT and medical device manufacturers needing product-security assurance, and multi-country buyers that want a single contracting party.
Trade-offs: As part of a global TIC group, billing rates and engagement cadence track closer to enterprise-paced than to SaaS-paced delivery.
4. Northwave Cyber Security
Northwave was founded in Utrecht in 2006. The company now has more than 275 employees across Benelux, DACH, and the Nordics, organized in three pillars (Business, Bytes, Behaviour). Northwave is the strongest "SOC plus pentest plus CERT" integrated provider in the Dutch market.
Headquarters: Utrecht, Netherlands.
Why Dutch buyers pick Northwave in 2026:
Intelligent Security Operations (ISO) launched 2014. Continuous monitoring, detection, and response tightly integrated with pentest and red team output.
CERT capability for managed detection and incident response across Europe.
Red team and TIBER assessments in scope.
ISO 27001 certified; Tech Accord signatory.
Behaviour pillar covers human-risk management, a complement to technical pentest work.
Best fit: Dutch mid-market and enterprise organizations that want one contracted partner for SOC, pentest, red team, and crisis exercises, with strong Benelux delivery depth.
Trade-offs: Pentest is one offering inside a broader managed-security portfolio rather than the primary product, so depth of pentest-specific research output is below the pure-play research firms.
5. Computest Security
Computest is Zoetermeer-based and a long-standing Dutch web, mobile, and API pentest firm. Best known publicly for advisory work and for productized DevSecOps integration with Dutch engineering teams.
Headquarters: Zoetermeer, Netherlands.
Why Dutch buyers pick Computest in 2026:
Web, mobile, and API specialization. Deep coverage of the application layer common to Dutch SaaS, e-commerce, and digital-product teams.
DevSecOps integration. Strong fit for engineering teams that want pentest output threaded into Jira, GitHub, and CI/CD workflows rather than landing as a PDF.
ISO 9001 and ISO 27001. Procurement-ready posture.
Mature reporting and remediation guidance. Reports geared to engineering action, not just auditor sign-off.
Best fit: Dutch SaaS and digital-product teams that want a Dutch-resident pentest vendor with a DevSecOps-first mindset and a mature engineering-friendly reporting style.
Trade-offs: Less famous internationally than Fox-IT or Secura; not the right fit for ICS/SCADA-heavy industrial buyers.
6. Tesorion
Tesorion markets itself as 100% Dutch, with more than 140 experts and a subsidiary (Compumatica) that builds Dutch cybersecurity products. The firm holds ISO 27001 and NEN 7510 certifications verified by DEKRA and operates the T-CERT incident-response team.
Headquarters: Leusden, Netherlands.
Why Dutch buyers pick Tesorion in 2026:
100% Dutch sovereignty. Important for some government-adjacent and regulated buyers with sovereignty preferences.
ISO 27001 plus NEN 7510. Healthcare-ready out of the box.
T-CERT continuous monitoring and incident response. Integrated with pentest output.
Compumatica subsidiary supplies Dutch-built cybersecurity hardware and software, useful for government and defence-adjacent buyers.
Best fit: Dutch organizations with sovereignty constraints, Dutch healthcare providers needing NEN 7510 evidence, and Dutch SMBs that want a single managed-security plus pentest partner with Dutch-language support.
Trade-offs: Cross-border reach is limited; bench size is smaller than Northwave or Secura; offensive research output is less visible than the larger firms.
7. Zerocopter
Zerocopter was founded in 2015 in Amsterdam as one of the early European hybrid crowdsourced testing platforms. The model combines a managed researcher community with structured pentest engagements (Vulnerability Disclosure Programs, bug bounty, and PTaaS-style work).
Headquarters: Amsterdam, Netherlands.
Why Dutch buyers pick Zerocopter in 2026:
Hybrid crowdsourced model. Access to a curated researcher community with breadth no single boutique pentest firm can match on a single engagement.
Bug bounty plus pentest under one contract. Reduces vendor management overhead.
Strong Dutch and EU customer base. Local-language support and EU data-residency.
Best fit: Dutch digital-first companies, fintechs, and government VDP programs that want crowdsourced breadth plus boutique-style management.
Trade-offs: Research depth on novel bug classes depends on which researchers happen to engage; less consistent than a senior in-house pentest bench. Buyers who want predictable methodology cadence prefer a pure-pentest firm.
8. The Big Four (KPMG, Deloitte, EY, PwC)
KPMG Netherlands, Deloitte Netherlands, EY Netherlands, and PwC Netherlands all sell penetration testing inside their broader cyber, risk, and assurance practices. Board-level Dutch buyers often default to the Big Four for the audit-adjacent assurance signal.
Headquarters: Global Big Four firms with substantial Dutch member-firm benches.
Why Dutch buyers pick the Big Four in 2026:
Board-room compliance signaling. ISAE 3000, SOC 2 (US-equivalent attestation), and integrated GRC reporting.
Audit-adjacent assurance. Pentest output threaded into broader IT audit and risk programs.
DORA and NIS2 program-level advisory beyond pentest itself.
Cross-border footprint. Strongest fit for multinational Dutch HQs that need consistent vendor coverage across multiple legal entities.
Best fit: Listed Dutch corporates, regulated financial institutions where the audit partner relationship is the pivot, and Dutch HQs of multinational groups.
Trade-offs: Pricing typically 3 to 5x boutique rates for equivalent scope. Offensive depth varies sharply by partner-level engagement; junior teams sometimes ship below boutique quality. Less likely to break novel ground than a research-led pentest firm.
Figure 3: Certifications matrix. Verified against each vendor's About page or certifications page. CCV Keurmerk Pentesten coverage is the procurement-default for Dutch public-sector tenders. CREST member-firm accreditation is the closest internationally-accepted equivalent. Sources: vendor pages, Het CCV certified bodies list.
Pricing reality in the 2026 Dutch market
Dutch pentest pricing tightened in 2026 as supply expanded and as NIS2 and DORA pulled more in-house security budgets toward continuous testing. The bands below reflect the EUR-denominated Dutch market median for the May 2026 research window; bespoke scopes and senior-only delivery sit at the top of each band.
Small web app pentest (single product, 1 to 3 user roles): EUR 4,500 to 12,000 per engagement.
Mid-size SaaS or mobile app (5 to 10 roles, 2 to 4 integrations): EUR 12,000 to 30,000 per engagement.
Network and infrastructure (internal plus external, 250 to 1,000 IPs): EUR 15,000 to 40,000 per engagement.
Cloud and red team (multi-cloud or attack-path-focused): EUR 30,000 to 90,000 per engagement.
Annual PTaaS subscription (continuous web app coverage): EUR 40,000 to 120,000 per year.
Big Four enterprise engagements: typically 3 to 5x the boutique numbers above.
TIBER-NL or DORA TLPT: multi-month programs typically starting EUR 150,000 and rising with scope.
Stingrai publishes its specific package prices at www.stingrai.io/pricing. Use the live page for current numbers; specific dollar or euro figures cited from memory go stale.
Figure 4: Typical 2026 EUR-denominated pentest pricing bands in the Dutch market. Bespoke scopes and senior-only delivery sit at the top of each band. Big Four engagements typically run 3 to 5x boutique rates for equivalent scope.
How to choose between these vendors
Three questions narrow the shortlist quickly.
Does the engagement require a CCV Keurmerk Pentesten certification by contract or policy? If yes, the shortlist is Fox-IT, Secura, Northwave, Tesorion, and any current CCV holder on the Het CCV certified bodies list. Stingrai partners with a CCV holder for the formal mark where required.
Is the buyer profile SaaS or DevSecOps-first, or board-room compliance-first? SaaS and DevSecOps buyers should weight Stingrai, Computest, and Zerocopter higher. Board-room compliance buyers should weight Fox-IT, Secura, and the Big Four higher.
Is the scope ICS, SCADA, OT, or product security? Fox-IT and Secura have the strongest Dutch records on industrial and product testing. Most application-pentest firms (including Stingrai's web-focused Snipe) are not the right fit.
For most Dutch SaaS and regulated-mid-market buyers in 2026, the shortlist that fits 80 percent of the use case is: Stingrai for offensive depth and AI-augmented continuous testing, paired with one Dutch CCV holder for any CCV-mandated work. The remaining 20 percent of Dutch buyers (defence-adjacent, OT, healthcare-sovereignty, board-level compliance) have purpose-built local choices on this list.
Frequently Asked Questions
Who is the best penetration testing company in the Netherlands in 2026?
Stingrai is the top recommendation for Dutch organizations buying pentest or PTaaS in 2026 on offensive-depth metrics: CREST firm-level accreditation as a Penetration Testing service provider, 18 published CVEs across the team (Ivan Spiridonov 10, Moaaz Taha 5, Victor Villar 3), 5.0 out of 5.0 across 19 Clutch reviews, and the Snipe AI pentest agent trained on more than 6,000 HackerOne reports. London, UK office serves Dutch and broader EMEA delivery and Toronto, Canada is HQ. Fox-IT, Secura, Northwave, Computest, Tesorion, and Zerocopter are the strong Dutch-native runners-up depending on whether the engagement needs CCV certification, integrated SOC and pentest, DevSecOps focus, NEN 7510 healthcare, or crowdsourced breadth.
What is the CCV Keurmerk Pentesten and is it required?
The CCV Keurmerk Pentesten is the Dutch national pentest quality mark, developed and administered by Het CCV (Centrum voor Criminaliteitspreventie en Veiligheid). The scheme renewed to version 2.0 effective January 1 2024; a new pentester qualifications list (version 3.0) became effective January 1 2025. Certification is performed by DEKRA, DigiTrust, or Kiwa. The mark is not legally mandatory across the board, but is procurement-default for Dutch public-sector tenders and many regulated-sector contracts. Non-Dutch buyers often accept CREST member-firm accreditation as an internationally-recognized equivalent.
How much does a penetration test cost in the Netherlands?
Typical 2026 Dutch market pricing: small web app pentest EUR 4,500 to 12,000, mid-size SaaS or mobile app EUR 12,000 to 30,000, network and infrastructure EUR 15,000 to 40,000, cloud and red team EUR 30,000 to 90,000, annual PTaaS subscription EUR 40,000 to 120,000 per year. Big Four (KPMG, Deloitte, EY, PwC) engagements typically run 3 to 5x boutique rates. TIBER-NL and DORA TLPT programs typically start EUR 150,000 and rise with scope.
Which Dutch firm is best for NIS2 compliance evidence?
Fox-IT, Secura, Northwave, and Stingrai are all credible for NIS2 evidence. Stingrai's pentest output supports your NIS2 documentation alongside SOC 2, ISO 27001, HIPAA, PCI DSS 4.0, NIST SP 800-53 and 800-171, and DORA evidence. For CCV-mandated tenders, pair Stingrai with one of the Dutch CCV holders for the formal mark.
Which Dutch firm is best for DORA Threat-Led Penetration Testing?
Fox-IT (intelligence-grade and TIBER-NL pedigree) and Stingrai (CREST-accredited firm-level Penetration Testing service provider with senior red-team certifications on the bench, OSCE3, OSCP, OSED, OSEP, CRTO, CRTE) are the strongest matches for DORA TLPT work. Northwave is also strong for the SOC-integrated phase of a TLPT program. The European Central Bank's TIBER framework and the Dutch local variant TIBER-NL operated by De Nederlandsche Bank are the operational predecessors to DORA TLPT.
Which Dutch firm is best for healthcare and NEN 7510?
Tesorion (ISO 27001 plus NEN 7510 certified by DEKRA, T-CERT for incident response), Secura, and Northwave are the strongest Dutch fits. Stingrai's pentest output supports HIPAA, ISO 27001, and NEN 7510 evidence; pair Stingrai with a Dutch healthcare-experienced GRC partner for the formal NEN 7510 audit.
Is penetration testing required by Dutch law?
Pentesting is not universally mandated by Dutch federal law, but is effectively required by every compliance framework Dutch organizations adopt: GDPR Article 32 expects documented testing of security controls; NIS2 (Cyberbeveiligingswet) expects management-board accountability for documented testing; DORA Article 26 requires Threat-Led Penetration Testing for in-scope financial entities from January 17 2025; NEN 7510 expects independent assurance for Dutch healthcare. Combined with sector contractual requirements and the Autoriteit Persoonsgegevens' breach-notification regime, pentesting is the practical baseline for Dutch organizations handling personal data, critical-infrastructure operations, or financial services.
What certifications should my Dutch pentest vendor hold?
At the individual level: OSCP, OSWE, OSED, OSEP, CREST CRT, and CRTO on the actual testers who will be on the engagement. At the company level: CCV Keurmerk Pentesten (for Dutch procurement) or CREST member-firm accreditation (internationally equivalent), ISO 27001, plus NEN 7510 for Dutch healthcare scopes. Beyond paper, check public CVE track record (Stingrai's team has 18 published CVEs), DEFCON and BSIDES talks, and named senior testers on the actual proposal.
Can a non-Dutch vendor work for Dutch buyers in 2026?
Yes. Many Dutch buyers contract international pentest firms for SaaS, cloud, web, and red team scopes that do not require a Dutch national mark. Stingrai serves Dutch buyers from its London, UK office during EMEA hours. For CCV-mandated public-sector or regulated-sector contracts, pair the international firm with a Dutch CCV holder, or use the international firm for the offensive work and a Dutch GRC partner for the audit-side mark.
How long does a Dutch pentest engagement take?
Typical durations in the 2026 Dutch market: small web app 5 to 8 working days; mid-size SaaS or mobile app 10 to 15 working days; network and infrastructure 8 to 15 working days depending on scope size; cloud and red team 15 to 30 working days; TIBER-NL or DORA TLPT programs 12 to 24 weeks end-to-end. Reporting cycle typically 5 to 10 working days after testing ends; retesting included for paid PTaaS subscriptions. Stingrai's Hybrid Pentest model collapses some of this cycle by running Snipe's AI agent in parallel with the manual pentest bench.
