Enterprise ASN reconnaissance for teams who take security seriously
ASNSPY provides enterprise-grade network reconnaissance tooling for security teams who need visibility into Autonomous System Number (ASN) infrastructure. We build tools that map attack surfaces, discover exposed assets, and identify security gaps across entire network ranges.
You can't protect what you can't see.
Open-source, enterprise-ready ASN reconnaissance
We believe professional security tooling should be accessible to everyone, while providing enterprise-grade features for teams that need them.
Full-featured ASN reconnaissance tool available on GitHub under MIT license. No restrictions, no limitations, no catch.
Everything in Open Source, plus enterprise integrations, compliance tools, priority support, and advanced automation.
Security tools should be accessible to everyone. Small teams, students, researchers, and hobbyists shouldn't be priced out of professional tooling.
Open source builds trust. You can audit every line of code, verify there's no telemetry, and ensure it meets your security standards.
Enterprise features fund ongoing development. Companies that need SIEM integration, compliance tools, and priority support pay for those features.
A thriving open-source community benefits everyone. Bug reports, feature requests, and contributions make the tool better for all users.
Five principles that guide everything we build
Professional tooling should be accessible. We're open source by design. The core tool is free forever, no limitations, no bait-and-switch.
Security tools handle sensitive data. We build compliance controls (SOC 2, ISO 27001, GDPR) from day one, not as an afterthought. Authorization prompts, sanitization, and audit logging are standard.
We don't replace your existing infrastructure. We integrate with Splunk, Elasticsearch, PostgreSQL, Slack‚¬"whatever you already use. No vendor lock-in, no ecosystem wars.
Every line of code is auditable. No telemetry, no phone-home, no hidden APIs. You control your data, you control the tool, you control where it runs.
Security teams are understaffed. Tools should work in CI/CD, cron jobs, and orchestration platforms without human intervention. Automation-ready by default.

What you can count on from ASNSPY
We're a security tool. We take our own security seriously‚¬"code reviews, dependency audits, minimal attack surface.
No telemetry, no tracking, no data collection. Your scans stay on your infrastructure.
We integrate with everyone, favor no one. Use the tools you already trust.
Features requested by users, not marketing teams. Your feedback shapes the roadmap.
Production-tested, backward compatible, maintained. We're in this for the long haul.
Comprehensive guides, real examples, clear explanations. No "read the code" cop-outs.
