NULLSQUARE 5 features
OpenVAS 5 features
  • In-depth Technical Writing
    NULLSQUARE (A. Jesse Jiryu Davis's blog) features deeply technical articles on Python, MongoDB, async programming, and other software engineering topics, providing thorough and well-researched content that goes beyond surface-level explanations.
  • Expert Author
    The blog is written by A. Jesse Jiryu Davis, a Staff Engineer at MongoDB and a core contributor to several open-source projects including PyMongo and Motor, lending significant credibility and authority to the technical content.
  • Open Source Contributions
    The site highlights and documents open source work, including projects like Motor (an async MongoDB driver for Python) and contributions to CPython, serving as a valuable resource for developers interested in these technologies.
  • Clean and Minimalist Design
    The website has a simple, distraction-free layout that focuses on content readability, making it easy to navigate and consume articles without clutter or excessive ads.
  • Conference Talks and Presentations
    The site archives talks and presentations given at major conferences like PyCon and MongoDB events, providing additional educational resources in video and slide formats alongside written articles.

Possible disadvantages

  • Niche Audience
    The content is heavily focused on Python, MongoDB, and async programming, which limits its appeal to developers outside of these specific technology ecosystems.
  • Infrequent Updates
    Blog posts can be published irregularly, with sometimes long gaps between new content, which may disappoint readers looking for a regularly updated technical resource.
  • Limited Interactivity
    The site functions primarily as a static blog with limited community interaction features such as comments or forums, reducing opportunities for reader engagement and discussion.
  • Sparse Navigation and Discoverability
    The minimalist design, while clean, can make it difficult to discover older or related content, as there is limited categorization, tagging, or search functionality to help readers find relevant articles.
  • Mixing of Personal and Technical Content
    The blog occasionally mixes personal reflections, Zen Buddhism writings, and photography with technical content, which may not align with the expectations of readers seeking purely technical resources.
  • Open Source
    OpenVAS is an open-source vulnerability scanning tool, which means it is free to use and the source code is available for customization.
  • Comprehensive Scanning
    It offers comprehensive vulnerability scanning capabilities, including a wide range of tests for network vulnerabilities, web application security, and compliance checks.
  • Regular Updates
    The tool receives regular updates, ensuring that it keeps up with the latest vulnerabilities and security threats.
  • Community Support
    OpenVAS has a strong community of users and developers who contribute to its development and provide support through forums and other channels.
  • Integration Capabilities
    OpenVAS can be integrated with other security tools and systems, enhancing its utility in a broader security infrastructure.

Possible disadvantages

  • Complex Setup
    Setting up OpenVAS can be complex and time-consuming, requiring a fair amount of technical expertise.
  • Resource Intensive
    Running OpenVAS can be resource-intensive, potentially requiring significant CPU and memory, especially during large-scale scans.
  • False Positives
    Like many vulnerability scanning tools, OpenVAS can generate false positives, which can result in additional effort to validate findings.
  • User Interface
    The user interface can be less intuitive compared to some commercial vulnerability scanners, potentially increasing the learning curve for new users.
  • Limited Real-Time Capabilities
    OpenVAS is more focused on periodic scanning rather than real-time vulnerability detection and management.

Questions & Answers

As answered by people managing NULLSQUARE and OpenVAS.

How would you describe the primary audience of your product?

NULLSQUARE's answer

Our primary audience consists of fast-growing tech startups and SMBs with 1–100 employees. The best-fit industries are SaaS, Fintech, and E-commerce. Our target champions are technical and executive leaders, specifically CTOs, CEOs, Founders, VPs of Engineering, and Heads of Engineering. Geographically, we focus on the MENA region (Jordan, UAE, Saudi Arabia, Egypt) and global English-speaking markets (USA, UK, Europe).

Which are the primary technologies used for building your product?

NULLSQUARE's answer

NullSquare operates on an internal runner architecture deployed inside the customer's own network. We utilize Docker sandboxing to isolate every scan in a container that is destroyed immediately upon completion. The platform relies on AI agents to run automated black-box and white-box penetration testing across web applications, APIs, and cloud infrastructure. Additionally, we leverage GitHub integrations to provide automated security reviews on every pull request.

Why should a person choose your product over its competitors?

NULLSQUARE's answer

NullSquare provides a superior alternative across several competitive dimensions:

Vs. Traditional Pentest Firms: Traditional firms charge $10,000–$30,000 and take 3–6 weeks. NullSquare is 10–100x faster, offering findings the same day at a fraction of the cost.

Vs. Manual Scanners (ZAP, Nessus): Scanners output raw, unvalidated data and require expert operators. NullSquare provides a complete platform with validated findings and automated compliance output.

Vs. Enterprise AI (XBOW): XBOW requires enterprise engagement and lacks public pricing. NullSquare is built for startups, featuring instant accessibility, a free assessment on signup, and transparent reports in minutes.

Vs. Open Source (Strix): Strix requires the customer to run and maintain the platform themselves. NullSquare provides a fully managed platform.

Who are some of the biggest customers of your product?

NULLSQUARE's answer

As a company founded in 2026, we are an early-stage startup actively acquiring our first customers. We strictly do not target enterprises with 500+ employees. Instead, our ideal customer profile focuses on fast-growing startups within specific verticals:

SaaS and Tech companies

Fintech startups

E-Commerce businesses

What makes your product unique?

NULLSQUARE's answer

NullSquare’s architecture guarantees stronger data privacy than any SaaS competitor through our internal private runner. Agents run directly inside the customer's own infrastructure within isolated Docker sandboxes. These sandboxes are destroyed immediately upon completion, ensuring customer code and scan data never persist on NullSquare's servers. Furthermore, NullSquare’s AI agents confirm exploitability before reporting, ensuring customers receive proven vulnerabilities instead of false positive noise. Every scan also automatically generates built-in compliance evidence for SOC2, ISO27001, HIPAA, and PCI-DSS.

What's the story behind your product?

NULLSQUARE's answer

Founded in Jordan in 2025, NullSquare was built to address a massive gap in the security market. The industry is shifting from periodic manual pentests to continuous automated security testing. However, early-stage startups and SMBs are heavily underserved—they face the exact same compliance deadlines and investor pressures as large corporations, but cannot afford the $10,000+ price tags of enterprise tools or consulting firms. NullSquare was created to give these fast-growing teams the capability of a dedicated security engineer at a fraction of the cost.

  • Link CVE to installed applications?
    Otherwise your on the right path checkout the open source Greenbones OpenVAS (this was Nessus before they closed source and became corporate) or Project Discovery Nuclei. Source: over 3 years ago
  • What should I be doing as the sole sysadmin for a company to keep up with security?
    Personally, I was lucky enough to get a license to Nessus for my own scanning, however you can use OpenVAS for some free to scan. Scanners aren't 100% correct no matter where you go but it'll give you some things to look at. OpenVAS. Source: over 4 years ago
  • Wanting to protect my own homelab
    Https://openvas.org/ OpenVAS is free and fairly capable. It might struggle cpu on a pi... Might need quite a bit of ram, but I'm hoping you've got some beefier kit in your stack. Source: over 4 years ago
