[ how it works ]
How automatedpenetration testing works.
01
Probe
Agents map your real attack surface, every endpoint, parameter, and auth flow, from your code, your OpenAPI specs, or just the live app.
02
Exploit
Hundreds of agents work real attack paths in parallel. They try to break expected behavior the way an attacker would, not run down a checklist.
03
Verify
Every issue is reproduced from a clean state. Unproven findings are dropped; what's left ships with impact, repro steps, and a fix.
[ reports ]
Every report yourstakeholders need.
The same pentest produces the right document for each audience. No rewriting, no extra work.
Executive summary
Risk posture and the findings that matter, for leadership.
Customer-facing report
Proves your security posture without exposing your stack.
Auditor report
Findings with technical detail and mapped to SOC 2 and ISO 27001.
Remediation report
What's fixed, what's left, and what changed, ready to share.

Pauses on real risk
When an agent finds something exploitable, it stops and shows you the full attack analysis before going any deeper.
Safe by default
Parameter confirms a finding and holds. It won't chain exploits or escalate unless you opt in.
Escalate on your terms
Choose a deeper follow-up on any finding. Results are tracked in place, on the same finding.
[ capabilities ]
Finding to fix.Fully automatic.
Point Parameter at your code and it runs the full loop on its own. Find, exploit, verify, and fix, with almost no false positives along the way.
Whitebox, greybox, or blackbox
Point us at a repo, an OpenAPI spec, or just a URL. Agents reason at scale with full context.
Watch it work, live
Launch in minutes and follow agents as they hunt. Re-test the moment you ship a fix.
Fixes, not just findings
High-confidence pull requests, generated and ready to merge and re-test.
Under 1% false positives
Every finding clears a separate validation pass before it ever reaches you.
[ coverage ]
Everything an attacker can reach.Tested before they get there.
Point us at your stack and agents map every endpoint, API, and auth flow, the same surface a real attacker would probe.
Web apps
SPAs, server-rendered apps, and everything in between.
Infrastructure
Cloud misconfigurations and exposed services.
APIs
REST, GraphQL, and gRPC, authenticated or not.
Auth flows
Sessions, OAuth, SSO, and multi-tenant boundaries.
Source code
Pull-request scanning that catches issues pre-merge.
AI / LLM apps
Prompt injection, tool abuse, and data exfiltration.
[ definition ]
What is automated penetration testing?
Automated penetration testing is a pentest run by software rather than a booked team, delivered as a service you can start whenever you need it. Parameter's agents attack your code, cloud, and dependencies on every release. When they find a vulnerability, they exploit it to prove it is real. Anything they cannot prove is dropped. First findings arrive within 24 hours.

[ pricing ]
Pricing that scales.Priced to your app, not per seat.
From a one-off audit to always-on coverage, pricing tracks the size and complexity of what you’re testing. No seats, no surprises.
Single App
Fixed scope
A time-boxed pentest of one application and its primary APIs, with a full audit report.
Audit-ready SOC 2 / ISO 27001 report
One app and its APIs
