Feature Comparison

RedVeil

Autonomous AI Attack Agents

This is the core magic of RedVeil. Forget simple vulnerability scanners. The platform deploys AI agents that are trained to think and act like human attackers. They don't just check for known flaws; they reason through complex, multi-step attack paths—like chaining a misconfiguration to a weak credential to achieve privilege escalation. This agent-driven approach uncovers the real, exploitable risks that automated tools miss and manual tests take too long to find, delivering depth at automated speed.

On-Demand Testing & One-Click Retesting

RedVeil demolishes the scheduling bottleneck. You can start a comprehensive test whenever you need—post-deployment, pre-release, or on a regular cadence—with just a few clicks. No more waiting for annual audit windows or consultant availability. My favorite feature is the one-click retesting capability. Once you've remediated a finding, you can instantly re-test that specific issue to confirm it's fixed, enabling a truly agile and continuous security remediation workflow.

Compliance-Ready Reporting Engine

Generating a professional report is often the most tedious part of a pentest. RedVeil automates this entirely. With one click, the platform generates polished, detailed reports tailored for different audiences: executive summaries for leadership, technical deep-dives for engineers, and formatted evidence for auditors. These reports are explicitly built to meet the evidence requirements of major frameworks like SOC 2, ISO 27001, and PCI-DSS, saving you countless hours of manual compilation.

Guided Remediation with Rune

Finding a critical vulnerability is only half the battle; fixing it correctly is the other. RedVeil's integrated AI assistant, Rune, acts as your on-demand security expert. It can explain complex findings in plain language, break down attack paths step-by-step, and provide clear, actionable remediation guidance. Think of Rune as having a senior security engineer in your Slack channel, ready to help your team understand and resolve issues faster.

Use Cases

RedVeil

Continuous Compliance Validation

For teams needing to maintain SOC 2, ISO 27001, or PCI-DSS compliance, RedVeil is a game-changer. Instead of a frantic, expensive scramble for an annual test, you can run targeted pentests on-demand throughout the year. This provides continuous evidence of your security posture, makes audit season far less stressful, and demonstrates proactive risk management to auditors and clients with fresh, compliance-ready reports.

Pre-Production & Post-Deployment Security Gates

Integrate RedVeil into your CI/CD pipeline or run it manually before a major release. You can spin up a test against a staging environment to catch critical, exploitable vulnerabilities before they hit production. Similarly, run a quick test after a deployment to ensure new code or infrastructure changes haven't introduced unexpected security risks, enabling true DevSecOps practices.

Third-Party & Supply Chain Risk Assessment

Before onboarding a new vendor or deploying a critical third-party application, you can use RedVeil to conduct an external security assessment. Gaining an independent, AI-driven perspective on their exposed attack surface provides valuable risk intelligence that a vendor's own security attestation might not reveal, helping you make more informed procurement and partnership decisions.

Security Team Force Multiplication

Small or overburdened security teams can use RedVeil to offload routine penetration testing work. The platform acts as a tireless junior analyst, handling the broad discovery and initial exploitation work. This frees up your senior human experts to focus on strategic initiatives, complex architectural reviews, and responding to the high-severity, nuanced issues that the AI surfaces.

Overview

About RedVeil

Let's be brutally honest: traditional penetration testing is broken for modern software development. The old model of waiting weeks for a consultant, paying a small fortune, and getting a single, static "point-in-time" snapshot is a relic of a slower era. It's completely at odds with teams that deploy code daily and need continuous security validation. RedVeil is the paradigm shift we've been waiting for. It operationalizes penetration testing by merging the deep, contextual reasoning of a human hacker with the relentless speed and scalability of AI software. Imagine spinning up a full, autonomous penetration test in minutes, not weeks, and having a detailed, actionable, and audit-ready report on your desk by the afternoon. This isn't just a faster scanner; it's a platform of intelligent AI agents trained to reason through multi-step attack chains, uncovering the exploitable risks that truly matter. For security teams, DevOps engineers, and compliance officers at startups and growing businesses, RedVeil offers a new standard: professional-grade security testing that finally works at the speed of modern software delivery.
