Questions & Answers

As answered by people managing NULLSQUARE and JustDocz.

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).

JustDocz's answer:

JustDocz is designed for professionals, businesses, and organizations that work with large collections of documents and need to find information inside them quickly. Typical users include: - Lawyers, advocates, law firms, and legal departments - Researchers and academic users - Media organizations, publishers, and journalists - Accountants, finance professionals, and auditors - Consultants and professional services firms - Small and medium businesses - Educational institutions and libraries - Knowledge workers with large document archives - Privacy-conscious users who prefer local document processing It is particularly useful for people working with PDFs, Office documents, scanned records, images, reports, contracts, invoices, spreadsheets, and multilingual archives.

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.

JustDocz's answer:

JustDocz is built as a local desktop application using a modern desktop and document-processing stack. Primary technologies include: - Tauri for the desktop application - TypeScript and JavaScript - SQLite for local data storage and indexing - Full-text and local search technologies - OCR technologies including Tesseract - Local document parsing and extraction tools - PDF and Office document processing libraries - Optional local AI integration through Ollama and supported local language models The architecture is designed around local processing so document indexing, OCR, search, and optional AI workflows can run on the user's computer

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.

JustDocz's answer:

JustDocz is a strong choice for users who want to search large local document collections without moving their files into a cloud platform. It focuses on a practical problem: users often remember something written inside a document, but do not remember the filename or folder. JustDocz helps solve that by searching document content rather than relying only on filenames. Compared with basic file-search tools, JustDocz adds full-text document indexing, OCR for scanned files and images, multilingual search, typo-tolerant and phonetic search, and optional local AI capabilities. Compared with cloud-first document search services, JustDocz is designed around local processing, which can be important for law firms, researchers, media organizations, accountants, consultants, and businesses handling confidential files. No account or signup is required to get started.

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

JustDocz's answer:

JustDocz is newly launched, and we are currently onboarding early users and organizations.

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.

JustDocz's answer:

JustDocz combines local document search, OCR, multilingual search, and optional local AI in a privacy-first Windows desktop application. Instead of relying only on filenames, JustDocz indexes the contents of PDFs, Office documents, scanned PDFs, images, spreadsheets, presentations, and other local files so users can search by what they remember from inside a document. A key difference is its local-first design. Documents do not need to be uploaded to a cloud search service simply to become searchable. This makes JustDocz especially useful for professionals working with confidential or sensitive information. It is also designed for real-world document archives containing a mix of file formats, scans, older documents, multilingual content, spelling variations, and files accumulated over many years.

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.

JustDocz's answer:

JustDocz was inspired by a real problem: finding information across years of accumulated professional documents. The idea came from seeing how difficult it had become to locate information across legal files collected over many years. Often, someone might remember a client name, court, type of case, location, or phrase from inside a document, but not the filename or folder where it was stored. The problem became even more difficult as documents increasingly arrived as scanned PDFs, images, email attachments, Office files, and other formats. Privacy was equally important. Legal and other professional documents can contain confidential information, so uploading entire document collections to external cloud services is not always appropriate. JustDocz was built to make these existing local document collections searchable while keeping document processing on the user's own computer.
