What is Nano EASM?
Nano EASM is a cybersecurity SaaS platform for External Attack Surface Management. It helps IT teams, security generalists, and small MSSPs discover internet-facing assets, scan for risk, monitor exposure changes, and prioritise remediation — without juggling multiple tools.
Not to be confused with the open-source Verilog assembler called “nanoasm” (used in retro hardware projects and the 8bitworkshop IDE). Nano EASM is a different product entirely — a modern cloud-hosted security platform for the web, not a hardware development tool. They share a similar name; they share nothing else.
What does External Attack Surface Management mean?
Your external attack surface is everything an attacker on the public internet can see and reach: domains, subdomains, IP ranges, exposed cloud services, certificates, third-party integrations. Most organisations don’t have a complete picture of theirs — shadow IT, forgotten subdomains, and misconfigured cloud assets accumulate over time. EASM is the discipline of continuously discovering, monitoring, and reducing that attack surface.
What Nano EASM helps you do
Discover external assets
Map subdomains, IPs, exposed services, and certificates from a single seed domain. Surfaces shadow IT and forgotten infrastructure.
Scan for risk
Quick, Standard, and Deep scans look for known vulnerabilities, misconfigurations, and exposure issues — with severity scoring and CVE references.
Monitor exposure changes
Continuous monitoring with change detection. Get alerted when a new port opens, a certificate is about to expire, or a finding appears.
Prioritise remediation
Each finding comes with a plain-English explanation and clear next steps. Export to CSV/PDF for ticketing, audit evidence, or client reporting.
Who is Nano EASM for?
- IT teams at small and mid-size organisations who don’t have a dedicated security operations centre but still need to know what’s exposed on the internet.
- Security generalists who want one platform that handles discovery, scanning, monitoring, and reporting — instead of stitching three or four tools together.
- Small MSSPs managing multiple client environments who need separate workspaces, separate billing, and exportable reports per client.
How is it different from a vulnerability scanner?
A traditional vulnerability scanner needs you to tell it what to scan. EASM starts with the question what do we have? — discovering the assets first, then scanning them. The output is a complete view of external exposure, not just a list of CVEs against assets you already knew about.
Get started
Nano EASM has a Free plan with no payment details required — add up to two assets, run up to five scans a month, and see what your external attack surface actually looks like. Upgrade tiers add more assets, monitoring, scheduled scans, integrations, and team seats.
