Continuous monitoring across your stack.
Monitor code, APIs, web apps, cloud, infrastructure and new CVEs, so risk is caught the moment it appears. A Continuous subscription keeps security tied to the pace of your engineering — every release, every newly exposed system.
From $899/month · The MCP fix loop and unlimited retests included
What your subscription covers.
Code-change coverage
Security checks run when repositories, pull requests and code paths change — not once a year.
Deploy-time testing
Validate new releases and staging environments before vulnerable changes reach production.
Attack-surface monitoring
Watch domains, services, APIs and cloud assets for newly exposed paths and configuration drift.
New threats & CVEs
Track new CVEs and threat activity against your stack as it changes, and test what applies to you.
Learns your environment
Prior scans, architecture context and resolved findings make each test more relevant than the last.
Threat & CVE alerts
Notify the right workflow when a validated issue appears, a regression returns or a new CVE applies.
Security-posture tracking
Track findings, fixes and recurring risk so coverage is visible across your teams and releases.
Monthly human testing
A security engineer tests your application by hand every month, plus the release tests you request.
Unlimited retests
A finding closes only when an engineer replays the original attack and it fails. Retest as often as you ship.
Automated monitoring runs daily; human testing runs as a monthly pass plus the release tests you request. A finding closes only when a Zentinel engineer replays the attack and it fails.
Find the risk. Fix the code. Prove the fix.
Map it
We map the surface the way an attacker would: what's reachable, who can touch it and where the boundaries are.
Attack it
A security engineer exploits and reproduces every finding by hand, within the scope you approve in writing.
Prove, fix and verify
Each finding is sent to your coding agent over MCP with the fix, and only our retest can close it.
Teams shipping every week.
High-velocity SaaS
When you deploy to production daily and a yearly snapshot is out of date the next morning.
Enterprise-bound
When buyers expect continuous assurance, not a one-time certificate.
Lean teams
Your application security team, without hiring the headcount to run it in-house.
Keep it tested every time you ship.
Testing only with written authorization, within the scope you approve.
