Trusted by security teams at
Two attack surfaces. One platform.
Your Codebase
“AI copilots write code in seconds. They introduce vulnerabilities just as fast.”
Engineering teams deploy dozens of times per day. AI assistants generate thousands of lines in minutes. Every commit is a potential entry point — and traditional scanners drown you in false positives. Pennrows deploys a reasoning AI agent that traces data flows across your entire codebase, verifies each finding through multiple analysis passes, and delivers the exact fix.
Your Leadership
“AI-crafted phishing has made the inbox the most dangerous surface in your organisation.”
Business email compromise cost enterprises $2.9 billion last year. The attacks are no longer clumsy — they are personalised, contextual, and indistinguishable from legitimate correspondence. Pennrows monitors executive inboxes with an autonomous AI agent that detects threats no rule-based filter catches, and builds a cross-account threat blacklist that protects your entire organisation.
Capabilities
Security that reasons, not just scans.
AI Code Analysis
Every commit, examined with the rigour of a senior security engineer.
Pennrows doesn’t pattern-match. It reasons. A Claude-powered agent reads your code the way an auditor would — tracing data flows, evaluating exploitability in context, and separating genuine risks from noise.
SQL Injection — user input flows to query without sanitisation
Suggested fix
const query = "SELECT * FROM users WHERE email = $1";
const result = await db.execute(query, [email]);
Executive Email Protection
Your leadership’s inbox, monitored real-timeå.
An autonomous AI agent connects to executive email accounts and evaluates every inbound message for phishing, business email compromise, and AI-generated social engineering — with a depth that static rules cannot match.

What Sets Us Apart
Capabilities no competitor matches.
We built Pennrows for teams that refuse to choose between depth and usability. These are the reasons security leaders switch.
Deep Reasoning Engine
Your code deserves more than pattern‑matching.
Pennrows doesn’t grep for known signatures. It reads your code the way a principal engineer would — tracing data flows across files, evaluating exploitability in the context of your stack, and discarding noise before it ever reaches your team.
Powered by Claude, Pennrows conducts multi-stage analysis on every commit. Each potential vulnerability passes through false-positive verification, contextual severity assessment, and production-ready fix generation — all before a single alert fires. The result is a finding feed your engineers actually trust.
Capabilities
- Multi-pass verification eliminates false positives at the source
- Data-flow tracing across files, modules, and dependency boundaries
- Sub-task parallelism for enterprise-scale repositories
- Production-ready remediation code generated alongside every finding
Exploit Scenario Generation
Not just “vulnerable.” Here’s exactly how an attacker gets in.
Every competitor tells you something is wrong. Pennrows tells you what happens next — a step-by-step exploit narrative that shows your team the blast radius before a single line of code is changed.
For every confirmed finding, Pennrows generates an AI-authored exploit scenario: a plain-language walkthrough of how an adversary would discover, weaponise, and escalate the vulnerability in your specific environment. It transforms abstract risk into concrete urgency — and gives security leaders the language they need to brief non-technical stakeholders.
Capabilities
- Step-by-step attack narratives tailored to your codebase
- Blast-radius estimation scoped to the affected service
- Stakeholder-ready language that bridges engineering and the boardroom
- Prioritisation shifts from severity labels to real-world impact
Confidence Scoring
Severity tells you what. Confidence tells you whether to act.
Every finding in Pennrows carries a numeric confidence score — a measure of the AI’s analytical certainty, not just a colour-coded label. Filter your backlog by conviction, not convention.
Traditional scanners assign a severity and leave you to guess whether the finding is real. Pennrows surfaces a confidence score from 0 to 1, derived from the depth of analysis, availability of context, and consistency across verification passes. High-confidence findings get fixed first. Low-confidence findings get triaged, not ignored — but they stop blocking your release pipeline.
Capabilities
- Numeric confidence (0–1) on every finding, not just traffic-light severity
- Derived from multi-pass analysis certainty and contextual completeness
- Filter, sort, and threshold your finding feed by conviction
- Reduces mean-time-to-remediate by surfacing what matters first
Scan Comparison — Delta View
See exactly what changed between any two scans.
Place Tuesday’s scan next to Friday’s and know, line by line, which vulnerabilities were introduced, which were resolved, and which have persisted. A forensic diff for your security posture.
Pennrows’s delta view is a side-by-side comparison that turns scan data into a release narrative. New findings appear in red, resolved issues in green, and persistent vulnerabilities carry forward with their full history. It is the single fastest way to answer the question every engineering manager asks before a deployment: “Are we better or worse than last time?”
Capabilities
- Side-by-side comparison of any two completed scans
- New, resolved, and persistent findings categorised automatically
- Metric deltas for every severity level and file count
- Makes every release auditable without manual diffing
Finding-Level Collaboration
Comment, assign, resolve — without ever leaving the finding.
Threaded discussions, status history, and team assignments live directly on each finding. No context-switching to Jira, no pasting links into Slack. The conversation stays where the vulnerability is.
Every finding in Pennrows is a collaboration surface. Engineers can comment with context, security leads can assign ownership, and managers can track the full lifecycle from detection through remediation. The status timeline records every transition — giving auditors a complete chain of custody and giving your team a single source of truth that eliminates “I thought you fixed that” moments.
Capabilities
- Threaded comment threads on every individual finding
- Full status history timeline for audit and compliance
- Team assignment and ownership tracking per vulnerability
- Eliminates tool-hopping between scanners and issue trackers

Questions & Answers
What you should know.
What makes Pennrows different from traditional SAST tools?
Traditional static analysis relies on pattern matching and produces overwhelming false positives. Pennrows uses a reasoning AI agent powered by Claude that traces data flows, evaluates exploitability in context, and verifies findings through multiple analysis passes. The result is dramatically fewer false positives and production-ready fixes delivered alongside every finding.
How long does it take to get started?
Most teams scan their first repository within five minutes. Connect your GitHub, GitLab, or Bitbucket account, select the repositories you want to monitor, and Pennrows handles the rest. Webhook-driven scans begin automatically on every push.
How does executive email monitoring work?
Pennrows connects to designated email accounts via read-only access and evaluates every inbound message for phishing, business email compromise, and AI-generated social engineering. Threats are flagged instantly and added to a cross-account blacklist that strengthens your defences over time. Pennrows never modifies, delays, or intercepts email delivery.
What roles and permissions does Pennrows support?
Pennrows supports five roles. Owners and Admins have full control over settings, billing, and team management. Developers can trigger scans, manage findings, and receive real-time alerts via email, Slack, and Google Chat. Compliance Leads (Business and Enterprise plans) get read access to code reviews and compliance data, a weekly compliance report, and real-time alerts for compliance-related issues. Stakeholders receive read-only access with a monthly executive security and compliance report.
What do non-technical team members see?
Stakeholders and Compliance Leads get a tailored experience. Stakeholders receive a monthly executive report with your health score, open findings, and compliance posture — no code or terminal required. Compliance Leads get that plus a weekly compliance-focused report and real-time alerts when compliance-relevant issues are detected.
What compliance frameworks does Pennrows support?
Pennrows maps findings to SOC 2, ISO 27001, and the OWASP Top 10. Compliance dashboards give auditors and board members a clear view of your organisation’s security posture, and exports are available in CSV and PDF formats. Compliance mapping is available on Business and Enterprise plans.
Is my source code stored on Pennrows servers?
No. Repositories are cloned into isolated, ephemeral containers for the duration of a scan and immediately purged upon completion. Pennrows retains only the structured findings, metadata, and generated fixes — never your raw source code.
How does the Pay As You Go plan work?
You connect your repositories and email accounts, and we bill based on the AI tokens consumed during scanning. Your card is charged monthly. This plan is ideal for small teams, independent developers, and anyone who wants enterprise-grade scanning without a fixed commitment.
What happens after the Business 3-day trial?
Your card is collected at checkout but not charged during the trial. After three days your subscription activates automatically at $599/month (or the annual rate if selected). You can cancel anytime during the trial at no cost.
Can I switch between plans?
Yes. You can upgrade from Pay As You Go to Business at any time from your billing settings. Downgrading is also available at the end of your billing period. Contact us to discuss Enterprise requirements.
How do notifications work across channels?
Developers and Admins receive real-time alerts for critical findings via email, Slack, and Google Chat. Compliance Leads receive real-time compliance-specific alerts. Stakeholders receive scheduled reports only. Every team member can customise their notification preferences from the dashboard.
Do you offer discounts?
