Continuous Security Testing That Keeps Pace With Your Developers

Your team ships every day. A test from six months ago covers an application that no longer exists.

Sybil watches your code and/or your live attack surface for changes every day, then tests what changed on the schedule you set. No source code required.

No manual kickoff. No waiting for the next pentest.

Continuous security testing vs. the alternatives

vs. continuous scanning

A scanner reruns the same signature checks on a loop and flags anything that might be a problem, leaving your team to sort through the noise. Continuous security testing looks at what changed and proves what's exploitable.

vs. continuous monitoring

Monitoring watches and alerts, but it can't tell you whether a vulnerability is exploitable. Continuous security testing validates each finding by exploiting it, so your team only sees what's real.

vs. "continuous" human services

A retainer with human testers still waits on researcher availability, so coverage happens when someone's free. An autonomous system holds whatever cadence you set and tests on demand in between.

vs. bug bounty

Bug bounty programs pay for volume, and triage and severity disputes can cost your team more time than the findings are worth. Continuous security testing validates exploitability before anything reaches you.

Why your current testing falls short

Security testing wasn't built for how fast software ships today. Coverage goes stale between tests, changes go live without anyone testing them, and keeping up takes people most teams don't have.

Testing is outdated as soon as you ship

A pentest captures one version of your application at one point in time. Your applications change every week, so every release after it adds surface area that test never covered.

Your attack surface changes frequently

New endpoints, features, and services go live across your applications, including the ones your team doesn't build. Most of it won't be tested until the next annual assessment.

Lean teams can't run continuous testing by hand

Keeping testing current means someone has to spot what changed, scope a test, kick it off, and chase the results, every week. Most security teams don't have that person to spare.

More findings doesn't mean more clarity

Security tools can surface more potential vulnerabilities than your team can reasonably investigate. Without validation, you're left figuring out what's actually exploitable and what to fix first.

Two ways to continuously test with Sybil

Use one path or both. Sybil watches what's changing across your live attack surface and in the code your team merges, checks as often as daily, and tests on the schedule you set.

Continuous Coverage for a black box application with GitHub off, showing new endpoints Sybil found in four attack surface areas.

Black box: no code access needed

Sybil re-crawls your live applications as often as daily, compares each crawl to the last, and flags new and changed endpoints. Crawl as an anonymous visitor to see what attackers see, or as any user role to test what's behind the login. Start with a URL and cover your whole footprint without connecting a repo.

White box: connect your code

Connect your repositories and Sybil turns every merge into a test plan. Sybil reads what changed, ranks each area by risk, then tests it in your live app with your source code as context, with a focus on business logic and access control.

Either way, findings land where your engineers already work:

Findings push to Linear, Jira, or GitHub Issues

Apply fixes with the AI coding assistants your team already uses

Click Retest and Sybil confirms the fix in under an hour

A human tester can't re-crawl every app every day or hold a weekly cadence across your whole portfolio without the cost climbing every time you add one. Automating both is what makes continuous coverage possible.

Continuous security testing with RunSybil

Cycle history for Acme Portal listing each weekly cycle, what changed, what Sybil tested, and a repeat finding first found in August.

Every cycle, Sybil learns more about your application, drawing on past runs and your knowledge base to give its agents richer context. That memory is what lets each test go deeper instead of starting over.

What you get every cycle:

A coverage view of exactly what Sybil tested, and what it didn't

Repeat findings that show when a bug was first discovered and when it came back

A record of what changed and what Sybil tested, even in a week with no findings

A full report with an executive summary, OWASP mapping, CVSS 3.1 scores, and CWE IDs

Carta is building continuous testing into its AppSec program with Sybil.

“The real shift left is in findings becoming detection patterns powering the appsec flywheel where we push less vulnerabilities and we build confidence as there is continuous and deeper coverage of our attack surface,” says Brad Freer, Senior Security Engineer at Carta.

You decide where a person steps in

Automated testing only helps if you trust what it will do. Every team handles oversight differently, so Sybil lets you choose where testing pauses for review and where it runs hands-off.

QUEUE A DRAFT

Sybil packages each cycle's test as a draft and notifies you. Nothing runs until someone on your team starts it. This is the default.

JUST RUN IT

Sybil packages the test and starts it automatically.

EDIT THE PLAN

Deselect any change area, exclude whole repositories, or adjust focus areas before a test runs.

STAYS IN SCOPE

A recommendation tells Sybil where to focus. It never widens what Sybil is allowed to test.

Frequently asked questions

What is continuous security testing?

Continuous security testing checks your applications on an ongoing basis instead of once or twice a year. Sybil watches for changes in your code and on your live attack surface as often as daily, tests what changed on the schedule you set, and validates every finding as exploitable before it reaches your team.

Is continuous security testing the same as continuous scanning?

No. Continuous scanning reruns the same signature checks and flags anything that might be a problem. Continuous security testing actively tests what changed and proves which findings are exploitable, so your team gets validated findings instead of another queue of alerts.

How is continuous security testing different from penetration testing?

A traditional penetration test covers one version of your application at one point in time, and it can take weeks to schedule. Continuous security testing keeps going after that: Sybil tests what changed on a recurring schedule, so coverage keeps up with what you ship.

Do I need to connect my source code?

No. In black box mode, Sybil re-crawls your live applications, flags new and changed endpoints, and tests them starting from just a URL. Crawl as an anonymous visitor or as any user role. Connect GitHub to add white box change testing, or use both.

How does Sybil decide what to test?

For white box apps, Sybil reads the diff of everything merged since the last test, groups the changes by the part of your app they affect, and ranks each by risk. For black box apps, it compares each crawl to the last and flags what's new. Each test plan explains what changed and what Sybil will focus on, and every recommendation is tied to an actual change.

How often does Sybil test?

Sybil checks for changes as often as daily and tests on a cadence you choose: weekly, monthly, or quarterly. Everything that changed since the last test rolls into the next one. You can also start a test whenever you need one, and set testing windows so nothing runs during releases or outages.

Can I review a test before it runs?

Yes. By default, Sybil queues each test as a draft and waits for someone on your team to start it. You can deselect change areas or exclude repositories first, or switch to "Just run it" and let Sybil start tests on its own. Either way, Sybil stays inside the scope you approved.

What happens if nothing has changed?

If nothing security-relevant changed, Sybil doesn't create a test. It records what it reviewed and why, so your team still has a record that the cycle happened.
