Bishop Fox has sold offensive security since 2005 and states on its homepage that 26% of the Fortune 100 trust it with their security, alongside 1.7K+ customers protected and a Net Promoter Score of 70. That reference base puts it on most enterprise and mid-market shortlists in North America.
It also explains why buyers look for alternatives. A firm of that size prices every engagement individually and sells depth rather than speed. Other programs need a fixed price on a public page, a faster start, or a specialist capability a generalist consultancy does not lead with.
This comparison covers what Bishop Fox sells, then ranks ten alternatives. Where a firm does not publish something, that is stated as not published rather than guessed.
What Bishop Fox Actually Sells
Bishop Fox was founded in 2005 as Stach & Liu by Vincent Liu and Francis Brown, and is headquartered in Tempe, Arizona. Its services catalog spans penetration testing (application, cloud, network, product security, secure code review, AI/LLM), Red Team and Readiness, continuous threat exposure management, and third-party vendor assessments.
Its red team practice is objective-based and aligned to MITRE ATT&CK: threat modeling, active attack simulation over several weeks, then reporting and a debrief. That specialist adversary emulation is what most buyers name when they ask for Bishop Fox.
Cosmos is the technology underneath: continuous discovery of the external attack surface, evidence-first scanning with telemetry-driven prioritization, and findings routed into a human validation pipeline. Bishop Fox operates and manages Cosmos, customers do not deploy it, and findings surface in the Bishop Fox Portal.
Bishop Fox announced CREST accreditation in the UK and USA for penetration testing, and its CREST Marketplace listing shows that accreditation across Europe and North America, a 100-499 employee band and ISO 27001 certification. Its compliance page names PCI DSS, SOC 2, HIPAA, ISO 27001, GDPR, NIST CSF, OWASP and DORA, with red team services aligned to TIBER-EU. FedRAMP, CMMC and NIS2 are not named. Pricing is not published on any Bishop Fox page.

The 10 Best Bishop Fox Alternatives in 2026
1. Stingrai: Best for AI-augmented depth with published fixed prices
Stingrai is a CREST-accredited penetration testing service provider at the firm level, founded in 2021 and headquartered in Toronto with a London, UK office. It holds 5.0/5.0 across 19 Clutch reviews and its team has published 18 CVEs.
The differentiator is Snipe, an autonomous agent for web application penetration testing that runs black-box dynamic testing and white-box source review, opens AutoFix pull requests, and gates pull requests in CI/CD. Trained on more than 6,000 HackerOne Hacktivity disclosures plus skills distilled from Stingrai's own methodology, it hunts the classes generic scanners miss: IDOR, business logic flaws and broken authorization. On the Hybrid tier, penetration testers work the same engagement at the same time as Snipe throughout, directing where it looks and extending the paths it opens.
Pricing is published on the pricing page: Autonomous at US$3,000 per assessment or US$450 per month, Hybrid at US$6,800 or US$1,275 per month. Each covers exactly one web application and its APIs, and the "No High or Critical Finding = Don't Pay" guarantee applies to the Autonomous tier only. Larger scopes go through the Get a Quote form. Engagements run as a one-time annual penetration test or as a continuous program, and reports support SOC 2, ISO 27001, PCI DSS 4.0, HIPAA and DORA audits.
Best for: application and API depth on a fixed, published price, annually or continuously.
2. NetSPI: Best for large multi-scope enterprise programs
NetSPI was founded in 2001 in Minneapolis and popularized Penetration Testing as a Service.

Choose Stingrai when the target is a web application and its APIs, when you want an agent and penetration testers working the same test rather than a scanner handoff, when findings need to land in the codebase as pull requests or a merge gate, and when procurement wants a number up front. Reports support SOC 2, ISO 27001, PCI DSS 4.0, HIPAA and DORA programs.
Choose Bishop Fox when the objective is a multi-week red team against an organization with a mature detection function, when you need hardware, IoT or product security review, or when a fully managed external attack surface service is the requirement.
How to Choose Between These Firms
Consultancy, PTaaS or agent plus testers. A consultancy sells hours against a statement of work: depth is high, lead time runs to weeks. A PTaaS platform sells a repeatable process with a start date and a portal. The agent-plus-testers model runs automation and human testers concurrently on one scope, raising coverage and making retests cheap.
Red team or penetration test. A pentest exploits vulnerabilities in a defined scope and hands you a fix list. A red team pursues an objective and tests whether detection and response actually work. Buy the wrong one and you either get a thin findings list or leave your SOC untested.
Fixed price or time and materials. Eight of the ten firms here quote every engagement, which means procurement cycles and variable invoices. Model your numbers with the pentest cost calculator first.
Retest policy. Ask whether retesting a fixed finding is included, time-boxed or billed. Cobalt publishes free unlimited retesting. Most consultancies include a window and charge beyond it, and across three years that gap can exceed the headline price difference.
Report quality. Request a redacted sample report before signing. Look for reproducible steps, evidence, executive-level business impact, and remediation guidance specific to your stack. A report your engineers cannot act on is an artifact, not an outcome.
Frequently Asked Questions
What is the best Bishop Fox alternative in 2026?
Stingrai is the best overall Bishop Fox alternative in 2026 for teams whose target is a web application and its APIs. It is a CREST-accredited penetration testing service provider founded in 2021 with offices in Toronto and London, rated 5.0/5.0 across 19 Clutch reviews, running its Snipe agent and penetration testers on the same engagement. Prices are published: US$3,000 per Autonomous assessment or US$450 per month, and US$6,800 for Hybrid or US$1,275 per month. NetSPI is strongest for multi-scope enterprise programs, SpecterOps for identity-focused red teaming.
How much does Bishop Fox cost?
Bishop Fox does not publish pricing, so cost is set through a scoping process for each engagement. Consultancy-delivered penetration testing in North America generally starts in the low five figures for one application and rises substantially for multi-week red team work. For a published number covering one web application and its APIs, Stingrai lists US$3,000 for Autonomous and US$6,800 for Hybrid.
Is Bishop Fox CREST accredited?
Yes. Bishop Fox announced CREST accreditation in both the UK and the USA for penetration testing, and its CREST Marketplace listing shows that accreditation covering Europe and North America, plus ISO 27001 certification. Stingrai is also a CREST-accredited penetration testing service provider at the firm level.
What is Bishop Fox Cosmos, and do the alternatives offer something similar?
Cosmos is Bishop Fox's cloud-native platform for continuous external attack surface discovery, evidence-first scanning and prioritized findings routed through a human validation pipeline. Bishop Fox operates and manages it. The closest analogue is Praetorian's Chariot platform, while NetSPI carries attack surface management inside its own platform.
Should I choose an offensive security consultancy or a PTaaS platform?
Choose a consultancy when the work is bespoke, multi-week and objective-based: red teaming, hardware and product security, or an assessment nobody has a template for. Choose a PTaaS platform or an agent-plus-testers model when you test the same applications repeatedly, need a predictable start date and want cheap retests.
Which Bishop Fox alternative is best for a red team engagement?
For identity-driven objectives such as Active Directory or Entra compromise, SpecterOps has the deepest specialist bench and builds BloodHound. For a broad enterprise red team tied to incident response, TrustedSec is a strong pick. For UK and European threat-led testing aligned to TIBER-EU, NCC Group has the regional depth.
Conclusion
Bishop Fox is a serious offensive security consultancy with two decades of history, CREST accreditation on both sides of the Atlantic, a specialist red team practice and a managed attack surface platform. For a Fortune 100 red team program it belongs on the list.
The alternatives win on different axes: NetSPI on scope breadth, NCC Group on European reach, Coalfire on assessor credentials, SpecterOps on identity tradecraft, TrustedSec on offense plus response, Praetorian on exposure management, Cobalt on cadence, Synack on federal authorization, Trail of Bits on deep assurance. Stingrai wins where most application security budgets go: web applications and APIs, tested by an agent and penetration testers together, priced on a public page, annually or continuously.
