Top Continuous Penetration Testing Providers In 2026

The best continuous penetration testing providers for most buyers in 2026 are Sprocket Security, for year-round testing where AI agents handle reconnaissance and human testers prove the real attack paths; Bishop Fox, for enterprise-scale continuous testing on its Cosmos platform with expert validation of every high-confidence finding; and Hadrian, for agentic testing that maps the full external footprint and pentests it continuously. This guide to the Top Continuous Penetration Testing Providers In 2026 covers seven more providers, from managed continuous red teaming to AI-led testing with humans in the loop.

Continuous penetration testing is not the same as PTaaS. A PTaaS platform changes how a pentest is bought and delivered, but you still schedule tests. A continuous provider tests all the time: it watches your attack surface for changes, tests new and changed assets as they appear and validates findings year-round, usually for an annual subscription. That is why this list leads with providers whose continuous offering is their core business and overlaps with our PTaaS providers list on only three names. We included providers that combine ongoing discovery with ongoing exploitation and some level of human validation, and compared cadence, human involvement, scope and deliverables using the companies’ own service pages. Buyers who want scheduled tests on their own terms may prefer automated penetration testing platforms.

Best Continuous Penetration Testing Providers In 2026

1. Sprocket Security — Year-Round Testing Driven By Real Changes

Madison, Wisconsin-based Sprocket Security built its business around continuous penetration testing rather than adding it to a consulting practice. After an initial baseline, testing becomes what the company calls a trickle tied to real changes: when new assets, services or subdomains appear, they are tested. AI agents handle discovery, reconnaissance and first-pass exploitation, and human testers validate findings and pursue the real attack paths.

Onboarding needs little more than your domains and IP ranges. You follow the attack narrative and findings in a portal as they are discovered, mark items ready for fixing, and Sprocket retests them. Retesting is unlimited, with no per-test, per-scope-change or per-engagement fees, and every finding comes with proof of exploitation and an owner rather than raw tool output. Sprocket also publishes a safety framework for its AI agents that maps to the OWASP Autonomous Penetration Testing Standard.

The attack surface management product can be started free, and changes it finds feed directly into testing. Sprocket provides attestation letters for SOC 2, PCI DSS, HITRUST and ISO 27001, is a CREST member and appeared in the 2025 GigaOm PTaaS Radar.

Best for: Mid-market and enterprise teams that want to replace a yearly external pentest with continuous, human-validated testing at a predictable cost.

2. Bishop Fox — Cosmos Continuous Testing With Expert Validation

Bishop Fox, the Tempe, Arizona offensive security firm, runs its continuous testing on Cosmos, a cloud-native platform it operates on the client’s behalf, so there is nothing to deploy. Cosmos builds and maintains a living inventory of your external attack surface, including domains, subdomains, cloud resources, network services and web apps, with daily checks that confirm which assets are reachable. The inventory updates as cloud estates grow, shrink or change through mergers.

Scanning is evidence-first: Cosmos collects technology fingerprints, screenshots and service metadata, then prioritizes exploitable risk rather than scanner noise. High-confidence findings pass through an expert human validation pipeline before delivery, so customers see confirmed issues in the Bishop Fox portal with a triage workflow. Cloud connectors cover AWS, Google Cloud, Azure, Cloudflare and Oracle, and validated findings sync both ways with Jira and ServiceNow.

Bishop Fox was named a Leader and Fast Mover in the 2026 GigaOm Radar for Attack Surface Management, and Equifax is a named Cosmos customer.

Best for: Large enterprises with complex, multi-cloud perimeters that want continuous testing with every critical finding confirmed by an expert.

3. Hadrian — Agentic Discovery And Continuous Pentesting Of The External Footprint

Hadrian was founded in Amsterdam in 2021 by ethical hackers Rogier Fischer and Olivier Beg with Maurice Clin, and raised a 40 million dollar Series B in 2026, bringing total funding to 65 million dollars. Its tagline is direct: know your attack surface, pentest it continuously.

The platform has two parts. Atlas provides continuous external exposure management, starting from your organization and mapping subsidiaries, domains, subdomains, IPs, certificates and cloud hosts, then keeping that inventory current. Nova runs agentic pentests on demand: agents sign in as different roles, learn how an app’s business logic works and chain small steps into real impact within the scope you set. Used together, Atlas finds exposures and Nova proves how far they go.

There is nothing to install, and Hadrian offers a free external scan. Named customers include McKesson, NBCUniversal, TotalEnergies and Amadeus. It holds SOC 2 Type 2 and maps evidence to DORA, NIS2 and ISO 27001.

Best for: Global organizations with many subsidiaries and brands that need their external footprint discovered and tested without manual scoping.

4. Praetorian — Praetorian Guard Agent Fleet With Fixed Testing Cadences

Austin-based Praetorian sells continuous offensive security through the Praetorian Guard platform, which combines attack surface management, vulnerability management, threat intelligence, attack path mapping, continuous penetration testing and breach and attack simulation. Testing is run by a fleet of specialized AI agents coordinated by an orchestrator, with each agent limited in code to the tool calls its specialty needs. The playbooks come from Praetorian’s own field engagements.

Guard is one of the few providers that publishes its cadence: perimeter testing weekly, authenticated testing every two weeks and cloud testing nightly. An annual assessment is included on dates you choose. You can task the orchestrator through chat, Slack or Teams, monitor agents mid-operation, or set a budget and let them run, and destructive actions are off by default. Guard covers seven attack surfaces, including perimeter, web and APIs, LLMs, cloud, code, internal Active Directory and social engineering, and integrates with more than 80 tools.

Praetorian pitches Guard as a way to consolidate ASM, vulnerability management, threat intelligence, BAS and annual pentesting spend into one program, and it still runs a separate professional services practice for red and purple teaming.

Best for: Security leaders who want to consolidate several exposure tools and the annual pentest into one continuous program with clear cadences.

5. Evolve Security — Continuous Pen Testing Validated By A US Offensive SOC

Chicago-based Evolve Security was founded in 2016 and moved into continuous penetration testing in 2018. Its continuous pen testing pairs automated testing at scale with validation by offensive security experts in its US-based Offensive SOC, which validates every finding before it reaches you.

Work is delivered through Darwin Attack, now at version 3.0. Findings are posted during testing rather than held for a final report, and critical findings include video walkthroughs. The platform scores risk by business function, asset criticality, attacker interest and threat intelligence instead of raw CVSS, and dashboards track posture over time. Evolve frames its service around the five CTEM stages and sells attack surface management and exposure remediation alongside continuous testing.

Evolve was named a Leader and Outperformer in the 2025 GigaOm Radar for PTaaS, and named customers include Xactly and OPENLANE.

Best for: Mid-sized and enterprise organizations that want every continuous finding confirmed by a dedicated US-based human team.

6. NetSPI — AI-Assisted Continuous Testing Beyond The Perimeter

Minneapolis-based NetSPI, which employs more than 350 in-house pentesters, offers continuous penetration testing as a separate service from its PTaaS. It describes the service as AI-powered assessments tailored to your risk profile and operational cadence, with human experts focused on high-impact analysis and AI mapping the attack surface quickly.

The main difference from most providers on this list is scope. NetSPI’s continuous testing covers external and internal networks, web apps, cloud and AI and LLM systems, not just the internet-facing perimeter. It pairs with NetSPI’s Attack Surface Visibility service, which runs weekly external discovery scans, weekly AWS and Azure configuration scans, daily dark web monitoring and look-alike domain monitoring.

Results land in The NetSPI Platform with live reports, manual validation and remediation tracking, and an MCP integration lets AI agents pull validated findings into tickets and alerts.

Best for: Enterprises that need continuous coverage of internal networks, cloud and AI systems as well as the external attack surface.

7. Rapid7 — Vector Command Continuous Red Teaming

Boston-based Rapid7 delivers continuous testing as Vector Command, a managed continuous red team service. Rapid7 runs constant reconnaissance of known and unknown internet-facing assets, then its red team experts safely exploit exposures using current attacker techniques, including phishing, external network assessment, breach simulation and validation of emergent threats.

The deliverables reflect the red team angle: same-day findings after successful exploitation, vetted multi-vector attack paths, a prioritized list of the exposures and assets most likely to attract attackers, and prescriptive remediation guidance. Rapid7 contrasts this with a traditional red team engagement, which is typically a one-month, point-in-time exercise.

Vector Command Advanced adds ongoing attack surface management and internal network testing, including an annual internal penetration and segmentation test for compliance.

Best for: Organizations that want ongoing, attacker-style testing of the perimeter, including phishing, managed by a large vendor.

8. Synack — Recurring AI And Crowd Testing With Trend Reporting

Synack’s continuous penetration testing runs recurring cycles through the year instead of one-off engagements. Built-in discovery finds web apps, APIs, cloud resources, hosts and external assets, recurring AI-led and human-led tests concentrate on the assets that change most, and researchers confirm exploitable findings before they reach your team. Trend reports show new, recurring and resolved risk over time.

Buyers can mix three offerings: Sara Continuous for recurring AI-led testing against an agreed scope, Sara AI Pentesting for targeted on-demand tests, and the Synack Red Team, more than 1,500 vetted researchers, for deeper year-round human coverage. Each finding includes evidence, severity, the affected asset and remediation guidance.

Best for: Enterprises and agencies that want a blend of AI and vetted human testers running on a recurring cycle.

9. Terra Security — Agentic Continuous Pentesting With Pentester Sign-Off

Terra Security, co-founded by Shahar Peled and Gal Malachi, raised a 30 million dollar Series A led by Felicis in 2025, bringing total funding to 38 million dollars. It describes its product as agentic AI continuous penetration testing with a human-in-the-loop mechanism: a group of fine-tuned AI agents tests the attack surface while human pentesters oversee critical decision points.

Coverage includes web apps, external and internal networks and AI red teaming of copilots, LLMs, MCP servers and agent behavior. Users work with the agents in Terra’s TORCH collaboration hub and can control each step. Findings are proven by exploitation and mapped to each organization’s business risk, and reports are signed by certified pentesters for SOC 2, ISO 27001 and HIPAA. Terra is a CREST member and recently added continuous network infrastructure pentesting.

Best for: Teams that want AI-speed continuous testing but need reports signed by human pentesters for auditors.

10. Raxis — Raxis Attack Unlimited Manual Testing

Raxis takes the most human approach on this list. Raxis Attack gives clients unlimited manual testing by senior US-based engineers for the length of the contract, with findings posted live in the Raxis One portal as soon as they are confirmed. Where most continuous providers rely on agents for breadth, Raxis relies on people.

Raxis One provides live progress updates, interactive findings, attack storyboards and remediation tracking, and retesting is included. The Atlanta firm has tested manually since 2011, publishes CVEs and supports PCI DSS, HIPAA, SOC 2, ISO 27001, GLBA and CMMC.

Best for: Teams that release often and want continuous coverage from human testers rather than AI agents.

How To Choose A Continuous Penetration Testing Provider

What Does Continuous Actually Mean?

Ask for the cadence in writing. Praetorian publishes weekly, biweekly and nightly schedules, Sprocket tests on change, and Synack runs recurring cycles. Find out how quickly a new asset is discovered and how quickly it is tested.

Who Validates Findings?

Most providers now use AI for breadth. The difference is human validation: Bishop Fox, Evolve and Sprocket put humans in front of findings, Terra has pentesters sign reports, and Raxis is fully manual.

Is Internal Coverage Included?

Many continuous programs focus on the external perimeter. If you need internal network, Active Directory or cloud coverage, NetSPI, Praetorian and Rapid7’s Vector Command Advanced go further. Our internal vs external penetration testing guide explains why both matter.

Does It Replace Your Annual Pentest?

Several providers include an annual assessment or attestation letters. Confirm your auditors accept continuous testing evidence, using our penetration testing for compliance guide.

How Does It Fit With Attack Surface Management?

Continuous testing depends on good discovery. Some providers include their own ASM, while others ingest your existing inventory. See our attack surface management platforms list if you need discovery first.

Frequently Asked Questions

What Is Continuous Penetration Testing?

Continuous penetration testing is an ongoing service that discovers new and changed assets and tests them throughout the year, rather than once or twice a year. It usually combines automated discovery and testing with human validation of findings.

How Is Continuous Testing Different From PTaaS?

PTaaS is a delivery model for scheduled pentests, with a platform for findings and retests. Continuous testing runs all the time and reacts to changes. Some vendors sell both, which is why NetSPI, Synack and Raxis appear on both lists. Read PTaaS vs traditional penetration testing for more.

Is Continuous Testing Worth The Cost?

For organizations whose attack surface changes weekly, usually yes, since new exposures get tested in days rather than months. For stable environments, an annual test plus scanning may be enough. Our penetration testing cost guide and how often should you run a penetration test help you decide.

Conclusion

Sprocket Security is the strongest pick for teams replacing an annual external test with change-driven, human-validated testing, Bishop Fox suits large enterprises with sprawling perimeters, and Hadrian fits global organizations that need agentic discovery and testing at scale. Praetorian, Evolve Security, NetSPI, Rapid7, Synack, Terra Security and Raxis each offer a distinct mix of cadence, scope and human involvement.

Ask every shortlisted provider for its testing cadence, a sample finding and a sample attestation before you sign. For scheduled testing instead, compare PTaaS providers, and for attacker-style objectives see red teaming companies. Explore more in the penetration testing hub.
