All-in-one application security for startups
Fencer covers the full application security stack: static code analysis, dynamic testing, dependency scanning, and secrets detection. Up and running in minutes, no security team required.
Why Fencer?
AppSec that fits how you build
Connect your stack and start scanning immediately, no complex configuration or security expertise required.
Fencer scans continuously so vulnerabilities don't sit undetected between penetration tests.
Fencer covers key technical controls and auto-generates evidence so you don't have to chase screenshots.
Capabilities
All your application security needs in one place
Catch vulnerabilities before they merge
Fencer scans your source code on every pull request and on a daily schedule, surfacing security vulnerabilities before they reach production. Findings appear inline in your PR — in GitHub, GitLab, or Bitbucket — so developers fix issues in the same workflow they already use.
- Severity levels: Critical, High, Medium, and Low so you know what to prioritize
- Scan history: Full record with timestamp, trigger type, and initiating user
- Assignable findings: Assign issues to developers and track resolution through Linear or Jira
- All major languages: No configuration required out of the box
Test your live application, not just your code
DAST finds runtime vulnerabilities such as SQL injection, cross-site scripting, broken authentication, and more. Fencer tests your application, APIs, and MCP servers on a continuous schedule, so your coverage keeps pace with your shipping cadence rather than waiting for the next pen test.
- Continuous coverage: Scheduled scans continuously detect issues as they appear
- Authenticated scanning: Tests endpoints that require login, not just public-facing routes
- No agent required: No code changes needed; Fencer tests from outside your application
- Pen test complement: Fills the gaps between annual pen tests with ongoing detection
Find exposed secrets before someone else does
Fencer scans your code repositories and hosting platforms for exposed secrets such as API keys, tokens, credentials, and private keys.
- Repo and platform coverage: Scans both code and the hosting environments where secrets leak
- Remediation guidance: Each finding includes specific steps to rotate and resolve the exposure
Know what's in your dependencies before it matters
Fencer inventories every open source package across your connected repositories and surfaces known vulnerabilities, license risks, and outdated packages. When a new CVE drops, you know immediately which repos are affected and how severe the exposure is — before you read about it somewhere else.
- Full dependency inventory: Every package across every connected repo, in one view
- License compliance: Flags GPL, AGPL, and other licenses that may create legal or acquisition risk
- SBOM generation: Produces a software bill of materials on demand for security questionnaires
- Transitive coverage: Catches vulnerabilities nested in dependencies of dependencies
What can you do with Fencer's application security capabilities?
Replace your patchwork of point solutions
Dependabot, a SAST tool, a separate DAST scanner: managing three tools that generate separate alerts in separate dashboards with no shared context is a full-time job. Fencer consolidates all four application security disciplines into one platform with one unified finding view.
Pass your SOC 2 application security controls
SOC 2 auditors want evidence of continuous vulnerability scanning, not a pen test report from last year. Fencer generates a timestamped record of every scan, finding, and resolution automatically and sends it to your GRC tool.
Catch vulnerabilities before your pen test does
Pen tests are valuable, but finding a critical vulnerability during an annual test means it was there all year. Fencer runs continuously so issues surface when they're introduced, not 11 months later.
“A lot of security products are built for a dedicated security team. Fencer takes a developer-first approach and meets you where you already are as a dev team, which makes it a much better fit for a startup like ours.”
