As answered by people managing NULLSQUARE and ImmuniWeb.
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.
ImmuniWeb's answer:
ImmuniWeb SA is a global application security company headquartered in Geneva, Switzerland. The company is profitable, cashflow positive and rapidly growing since its incorporation in 2019. The award-winning ImmuniWeb® AI Platform helps over 1,000 customers from more than 50 countries to discover, test and protect their web and mobile applications, APIs and micro services, cloud and network infrastructure, and third-party systems processing corporate data.
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).
ImmuniWeb's answer:
Companies and organizations of all sizes.
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.

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

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.
ImmuniWeb's answer:
ImmuniWeb leverages the award-winning AI technology for intelligent automation and acceleration of laborious tasks and processes, saving as much as 90% of human time compared to traditional MSSPs. Our security experts handle only to the most complicated tasks and processes that truly deserve human intelligence thereby offering the best quality and best price of service on the global market.
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.
ImmuniWeb's answer:
Providing one of the most comprehensive offering in the industry, the Platform covers 20 use cases related to cybersecurity, compliance and privacy, including Attack Surface Management, Dark Web Monitoring, Web and Mobile Penetration Testing, Cyber Threat Intelligence, Third-Party Risk Management, and more. ImmuniWeb’s proprietary technology is a recipient of numerous awards and industry recognitions for practical usage of AI, including Gartner Cool Vendor, IDC Innovator and SC Awards Europe. Our Machine Learning technology stack considerably reduces application security costs of our customers by intelligent automation of laborious and time-consuming tasks, significantly accelerating those tasks in parallel.
