Feature Comparison

RedVeil

Intelligent AI Attack Agents

RedVeil deploys advanced AI agents trained to think and act like human attackers. These agents don't just run simple scans; they reason through complex, multi-step attack chains to uncover deep-seated vulnerabilities and exploitable risks that traditional tools might miss. This provides your team with the depth of a manual assessment, revealing the true potential impact of security flaws within your environment.

On-Demand Testing & One-Click Retesting

Eliminate the lengthy scheduling and scoping calls associated with traditional pentests. With RedVeil, your team can initiate a full-scale penetration test whenever needed—post-deployment, before a major release, or as part of a regular security cadence. The one-click retesting feature allows for immediate validation of fixes, creating a fast, collaborative feedback loop between developers and security.

Compliance-Ready Reporting

Generate professional, detailed reports tailored for various stakeholders with a single click. These reports are structured to meet the rigorous evidence requirements of major compliance frameworks like SOC 2, ISO 27001, and PCI-DSS. This streamlines audit preparation, saving your team countless hours and ensuring you can confidently present findings to auditors, executives, and engineering teams alike.

Guided Remediation with Rune

RedVeil includes Rune, an integrated security expert that provides clarity and support throughout the testing process. Rune assists with initial scope setup, breaks down complex findings into plain language, and offers step-by-step remediation guidance. This feature ensures your entire team, from engineers to managers, can understand and act on security insights effectively, fostering a unified approach to risk mitigation.

Frequently Asked Questions

RedVeil FAQ

Does RedVeil perform a real penetration test?

Yes, RedVeil performs authentic penetration testing. It moves beyond basic vulnerability scanning by deploying AI agents that autonomously reason, exploit, and chain vulnerabilities together to simulate the multi-step attack paths a human hacker would use. This results in findings that are verified, exploitable, and come with clear evidence and context.

How many penetration tests can I do with my annual subscription?

Your testing capacity is based on an "Agent Ops" effort model. For example, the Perimeter plan includes 500 Agent Ops annually, and the Full Coverage plan includes 2,500. This model allows for flexible, on-demand testing throughout the year. You can run multiple smaller tests or fewer in-depth assessments, aligning security efforts directly with your team's development and release cycles.

Can I use RedVeil's reports to meet my compliance requirements?

Absolutely. RedVeil's reports are specifically engineered to be audit-ready for major compliance frameworks including SOC 2, ISO 27001, and PCI-DSS. They provide the detailed evidence, executive summaries, and technical findings that auditors require, helping your team efficiently demonstrate a consistent and proactive security assessment process.

What types of testing do you offer? Is authenticated testing supported?

RedVeil currently offers comprehensive external web and network penetration testing. Authenticated testing, which allows the AI agents to assess an application while logged in as a user, is a supported and critical method for finding vulnerabilities that are only visible post-authentication, providing a much deeper security analysis.
