AI-Powered Network Security Audits Without Data Exposure.
NSAuditor AI is an open-core, AI-powered network security audit platform that runs agentless, read-only, and entirely on your infrastructure. Nothing is installed across your estate, credentials are read-only by design, and nothing goes to Nsasoft. Beyond the scan’s own traffic (your targets and local segment, DNS, your own cloud’s APIs) and NIST’s public NVD API for CVE matching (off with NSAUDITOR_OFFLINE_ONLY=1 and a local NVD store), every outbound path is opt-in and off by default.
With 56 plugins for networks and AWS, Azure, and GCP, one scan delivers risk-scored security findings, exploit-first prioritization using CISA KEV and FIRST EPSS, MITRE ATT&CK mapping, and auditor-ready evidence mapped to 8 compliance frameworks: SOC 2, HIPAA, NIST CSF 2.0, PCI DSS v4.0.1, ISO/IEC 27001:2022, CIS Controls v8, GDPR Article 32, and NIST SP 800-171 Rev 2.
Evidence packs include SHA-256 chain-of-custody manifests and opt-in RFC 3161 trusted timestamps. Operator-held Ed25519 signatures can be verified offline. NSAuditor AI supports air-gapped environments and reports evidence gaps explicitly—never claiming an unassessed surface is secure.
One scan. Technical security assessment. Eight compliance frameworks. Verifiable evidence. Zero data exfiltration.
An open-core scanner with risk-scored findings, threat intelligence, and octa-framework compliance evidence — SOC 2, HIPAA, NIST CSF 2.0, PCI DSS v4.0.1, ISO/IEC 27001:2022, CIS Critical Security Controls v8, GDPR Article 32, and NIST SP 800-171 Rev 2 — built so your audit trail holds up to a CPA-firm review, a QSA RoC walkthrough, an ISO Stage 2 assessment, a CIS-CAT self-attestation, and a GDPR Article 32 review.
Risk-Scored Prioritization
Every finding carries a composite risk score — severity × exploitability × impact × exposure — so the queue sorts worst-first, and an operator suppression workflow tracks accepted-risk and false-positive dispositions with expiry.
Findings are mapped to MITRE ATT&CK techniques with kill-chain context, so you can show your CISO what an attacker would actually do — not just CVE noise.
One scan produces eight auditor-ready evidence packs: SOC 2 (AICPA TSC 2017), HIPAA §164.312 Technical Safeguards, NIST CSF 2.0, PCI DSS v4.0.1 (sub-requirement-level for QSA RoC; every citation derived from the standard itself), ISO/IEC 27001:2022 (per-Annex-A-code with Statement of Applicability discipline), and CIS Critical Security Controls v8 (per-Safeguard with the Implementation Group cumulative discipline — IG1 cyber-insurance baseline / IG2 / IG3; no-certification-body attestation via CSAT / CIS-CAT Pro), and GDPR Article 32 (Security of Processing — infrastructure substrate for Art. 32 only, not GDPR compliance; 4/5/2 across 11 sub-measure units), and NIST SP 800-171 Rev 2 (evidence substrate for CMMC Level 2 preparation — all 110 Rev 2 requirements enumerated; 2/49/59). SHA-256 chain-of-custody sidecars you can verify offline, and opt-in outbound push to Vanta, Drata or Secureframe. Zero BAA required.
A network security audit is a systematic review of your network — hosts, ports, services, configurations, and cloud accounts — to find vulnerabilities, misconfigurations, and compliance gaps before an attacker does.
NSAuditor AI runs that audit locally: it discovers live hosts and services, fingerprints them with safe, non-destructive probes, matches those versions against CVE data offline, maps each finding to MITRE ATT&CK, and generates auditor-ready evidence for eight frameworks — SOC 2, HIPAA, NIST CSF 2.0, PCI DSS v4.0.1, ISO/IEC 27001:2022, CIS Controls v8, GDPR Article 32, and NIST SP 800-171 Rev 2 — from a single scan. Unlike SaaS scanners, every step runs on your own infrastructure, so a complete network security audit happens with zero data exfiltration.
Need cloud coverage? NSAuditor AI Enterprise extends the audit across AWS, GCP, and Azure with the full octa-framework compliance engine, air-gapped operation, and continuous monitoring (CTEM).
Watch: how do you actually run a network security audit on a cloud account in 2026?
A seven-minute how-to in six steps: scope it before you scan, use read-only credentials, check the scan actually audited, read the findings the way your auditor will, hand over what you did not examine too, and let the auditor verify it with standard shasum and openssl.

Three editions
Free, Pro, and Enterprise
Start with the MIT-licensed Community Edition. Upgrade only when you need CVE matching and risk-scored prioritization, compliance evidence, or cloud scanners.
EE 1.1.0 — Pro delta / trend reports, shipped in Community 0.2.55
Pro and Enterprise now answer the question every client asks next — did we actually get better since the last scan? — with a delta report of what is new, what is resolved and what changed severity. When the report can see that a finding was not measured the same way twice — a host that was not scanned; a plugin that did not run, errored or timed out; an evidence gap such as AccessDenied; a region, subscription or project the other scan left out; a TCP port the port scanner saw open that stopped answering — it files the finding as not-comparable, with the reason on the row, instead of calling it resolved: a finding that could not be compared is not a finding that was fixed. That port check reads only TCP ports, so a UDP-only finding that disappears can still read as resolved. Beside the comparison the report states that framework-enumeration movement is not evaluated in this release, and the baseline’s integrity state (a baseline scanned before 1.1.0 carries no integrity digest); when either run holds analysis-agent findings, it adds that their scope comes from the license tier. Known limit: two scans of one host that finish in the same second into the same output directory share one evidence directory, and the later run’s files replace the earlier run’s; this release refuses the overwritten run at report time, the overwriting scan does not yet warn, and a fix is planned for the next release. Enterprise Edition 1.1.0 is the current release, published 2026-09-28 alongside Community Edition 0.2.55 and the agent-skill package 0.2.53. Coverage: all eight coverage matrices unchanged since EE 1.0.0.
29 Enterprise auditors, 56 plugins overall, all eight frameworks. The Community Edition floor is 0.2.55 or newer — install Community Edition first. See the Enterprise plugin catalog →
