Penetrify replaces the once-a-year manual penetration test with an autonomous AI red team that runs whenever you deploy. Point it at a target and the agent handles the whole engagement itself - reconnaissance, authentication and authorization testing, exploitation, and multi-step attack chaining - returning a clear report with reproduction steps and fixes in minutes, with no security expertise required.

Unlike DAST scanners that only flag known patterns, Penetrify proves what an attacker can actually do, so it catches broken access control, IDOR, SSRF, and business-logic flaws as well as the full OWASP Top 10 and hundreds of other vulnerability classes. It tests web applications, REST and GraphQL APIs, and infrastructure, and plugs into GitHub Actions, GitLab CI, and a REST API for continuous coverage.

Designed for developers, founders, and lean security teams, it delivers the output of a $10,000โ€“$50,000 manual pentest as an ongoing subscription from $100/month - five plans up to Enterprise at $5,000/month, with a free trial. Built by a team with 20+ years in production security; founded in 2025 in Brno, Czech Republic.

Nullstack features and specs

  • Full-Stack Capabilities
    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.
  • Component-based Architecture
    Promotes the use of components, encouraging modularity and reusability of code, which can improve maintainability and scalability of applications.
  • Hot Module Replacement
    Supports HMR, allowing developers to see immediate changes in their applications without refreshing the entire page, improving development efficiency.

Possible disadvantages of Nullstack

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Analysis of Penetrify.cloud

Overall verdict

  • I don't have verified, specific information about Penetrify.cloud, as it appears to be a lesser-known or possibly new service without substantial independent reviews, security audits, or established reputation data available to me. Before using it, especially for security/penetration testing purposes, thorough independent research is strongly recommended.

Why this product is good

  • Limited public information or third-party reviews are available to verify claims of quality or reliability
  • No verifiable track record, certifications, or client testimonials could be confirmed
  • Security and penetration testing tools require high trust, and unverified providers carry inherent risk
  • Domain and branding suggest a niche cybersecurity tool, but legitimacy and effectiveness are unconfirmed

Recommended for

  • Not recommended without independent verification
  • Users should first check for company transparency, contact information, and business registration
  • Security professionals should look for peer reviews, case studies, or industry recognition before adoption
  • Consider established, well-reviewed alternatives in the penetration testing space unless you can independently verify this service's credibility and safety

Questions & Answers

As answered by people managing Nullstack and Penetrify.cloud.

What makes your product unique?

Penetrify.cloud's answer:

Most tools scan - they flag patterns that might be vulnerable. Penetrify exploits: an autonomous AI agent actually attacks the application, chains weaknesses into multi-step attack paths, and proves real impact, the way a human pentester would. It does this from just a URL, with no operator or security expertise needed, and runs continuously on every deploy through your CI/CD pipeline. The result is penetration-test depth - including authorization, IDOR, and business-logic flaws that scanners miss - delivered as an always-on SaaS instead of a once-a-year engagement.

Why should a person choose your product over its competitors?

Penetrify.cloud's answer:

  • vs. manual penetration testing: results in minutes instead of 1โ€“3 weeks, from $100/month instead of $10,000โ€“$50,000 per engagement, and continuous on every release instead of once or twice a year.
  • vs. DAST scanners (Burp Suite, Acunetix, OWASP ZAP): Penetrify exploits and chains vulnerabilities rather than only detecting known signatures, so it catches broken access control, IDOR, SSRF, and business-logic flaws those tools typically miss - and it's fully autonomous, requiring no manual operator.
  • vs. other AI security tools: true end-to-end autonomy (URL in, exploit-proven report out), native CI/CD integration, and developer-focused reports with reproduction steps and remediation.

How would you describe the primary audience of your product?

Penetrify.cloud's answer:

Development teams, startups, founders, and SMBs - fast-shipping teams that need continuous security coverage but don't have the budget for repeated manual pentests or an in-house offensive-security specialist. Also DevSecOps engineers who want a real penetration test wired into the build pipeline rather than a periodic audit.

What's the story behind your product?

Penetrify.cloud's answer:

Penetrify was founded in 2025 in Brno, Czech Republic, by Viktor Bulanek (MSc IT Security, 20+ years in security, four-time CTO). After years building and securing production systems, he kept seeing the same gap: startups were priced out of $10kโ€“$50k manual pentests and stuck with once-a-year testing that couldn't keep up with weekly deploys. So the team built an autonomous AI agent that runs the same methodology a senior security engineer would - continuously, and at a price a side project can justify. Penetrify is operated by Algofy s.r.o.

Which are the primary technologies used for building your product?

Penetrify.cloud's answer:

Penetrify runs on AWS serverless infrastructure (Lambda, containerized agents, S3, CloudFront). The autonomous testing agents are powered by frontier large language models, including Anthropic's Claude. The backend is a Python/FastAPI API; the web app is built with React and TypeScript.

Who are some of the biggest customers of your product?

Penetrify.cloud's answer:

As a security vendor we keep our customer list confidential - clients generally prefer not to publicize who runs their penetration testing. Penetrify is used primarily by startups, SaaS companies, and software development teams that ship frequently and need continuous security coverage.
