Agentic Pen Testing

Prove What’s Exploitable, Then Fix It.

AI coding tools change applications faster than periodic penetration tests can keep up. Agentic Pen Testing tests your live application to prove which vulnerabilities can actually be exploited, using context from your code, cloud, runtime, and business.

Proven findings go straight to developers with proposed fix pull requests and automatic re-testing, so teams spend their time on demonstrated risk instead of theoretical findings.

Software Changes Daily. Proof of Risk Shouldn't Wait for the Next Test.

AI accelerates development

AI coding tools change how quickly teams generate, modify, and ship software, and the attack surface changes with every release.

Manual testing is periodic

Traditional penetration tests are manual, time-intensive, and performed at fixed intervals, so the application keeps changing between tests.

Frequency alone isn’t enough

Running tests more often helps. If a vulnerability is only proven exploitable after it reaches production, teams are a

Proof beats potential.

Scanners report potential vulnerabilities. Teams still need to know which ones can be exploited in their environment before they decide what to fix first.

Finding a Vulnerability Isn't the Same as Proving It.

Code scanning, including AI SAST, finds potential vulnerabilities early and at scale. Agentic Pen Testing picks up where scanning stops. It tests the running application to show whether a weakness can be exploited, then uses what Arnica knows about your code, cloud, and business to show how much it matters.

The result is a clearer line between actionable risk and potential vulnerabilities, so security teams can focus on what matters most.
HOW IT WORKS

Four Sources of Context. One Proven Result.

Most tools look at one layer at a time. Agentic Pen Testing combines four, so each finding is tested and understood in the context of how your application is built, deployed, and used.
Source Code
Findings and context from SAST, AI SAST, software composition analysis, and infrastructure as code.
Cloud
Awareness of where the application runs, including AWS, Azure, GCP, and containerized environments.
Runtime
Agents interact with the live application to test whether a suspected weakness can actually be exploited.
Business context
Architecture diagrams, design documentation, threat models, developer feedback, and application hotspots show what matters most.
Prove exploitability
Agents test the live application with all four sources combined
What you get
Proven, exploitable findings
Proposed fix pull requests
Automatic re-testing
Alerts on proven critical issues
WHY ARNICA

Built for Teams That Ship Continuously

Agentic Pen Testing is designed around how modern development works, from the code change to the fix.
01
Full-Stack Context
Source code, cloud, runtime, and business context are evaluated together, so you prioritize demonstrated risk.
02
One-Click Onboarding
Test accounts and MFA are handled automatically, with endpoint and API discovery and VPN access for internal apps.
03
SDLC-aware Testing
Run full tests when they make sense, or incremental tests based on code changes, without retesting unchanged code.
04
Automated Workflows
Proposed fix pull requests, automatic re-testing, and alerts on proven critical issues, plus human review when needed.
05
Efficient Testing
A smart model router picks the model, testing harness, and context for each task, matching resources to the scenario.
A MORE COMPLETE APPROACH TO APPLICATION SECURITY

Security Across the Software Development Lifecycle

Prevention, detection, validation, and remediation work best as one loop. Each stage makes the next one more useful.
01
PREVENT →
Agentic rules reduce insecure coding decisions in AI-assisted workflows before code reaches review.
02
DETECT →
AI SAST finds potential vulnerabilities across code and development workflows at scale.
03
VALIDATE →
Agentic Pen Testing proves which of those risks can be exploited in the running application.
04
REMEDIATE
Developers get proven findings, fix pull requests, and re-testing inside the workflows they already use.

Frequently asked questions

What is Agentic Pen Testing?

Agentic Pen Testing is Arnica's ability to prove exploitability against a live system. It combines runtime testing with context from source code, cloud environments, application architecture, and the business to show whether a potential vulnerability is a real, exploitable risk.

How is it different from continuous penetration testing?

Continuous testing increases how often an application is tested. Agentic Pen Testing is SDLC-aware: it can run incremental tests based on code changes, connects results to fixes and re-testing, and uses code, cloud, and business context to show what matters. Frequency alone doesn't tell you which risks to fix first.

How does it relate to AI SAST?

AI SAST identifies potential vulnerabilities in code. Agentic Pen Testing tests the running application to prove which of them can be exploited. The two work together.

What does onboarding involve?

Agentic Pen Testing is designed to minimize manual setup. It can create accounts, handle MFA, discover endpoints and APIs, and connect over VPN to test internal applications, subject to supported configurations.

When is it available?

A controlled rollout begins November 5, 2026. To learn more or request a demo, talk to us.

Do I need a credit card to sign-up for a free trial?

Nope. There are no hidden clauses, no strings attached. You won't be signed up automatically at the end of your trial. At the end of the 14-day trial, you will be moved to the (forever) Free account version, and given the option to upgrade.

How does Arnica define Identities and Identity count?

Arnica defines Identities as any users and other contributing entities that contributed code and/or had PR activity during the last 90 days. To ensure Identity count is accurate Arnica removes duplicates across orgs. Groups of contributors, Assets, and Orgs themselves are not included in the Identity count.

Can I upgrade my plan after signing up?

Yes. You can upgrade your plan at any time within the app.
