External Attack Surface Management

You can't defend
what you don't know you own.

Nano EASM helps IT teams, security generalists, and MSSPs move from one-off scanning to continuous external exposure management — discover hidden assets, monitor exposure changes, catch employee credentials in breach data, and turn every finding into a clear next step. Try a real scan against your own domain — no signup, no card, no demo call.

Capabilities

Everything you need to manage
your attack surface

Find what you forgot you owned

Shadow IT, contractor leftovers, abandoned cloud assets. Add a root domain — 12 passive and active intelligence sources surface every subdomain, IP, and service across your external surface.

Multi-Engine Scanning

Scan with 9 purpose-built engines across network, web, and certificate attack surfaces. Choose Quick, Standard, or Deep profiles — or schedule recurring scans.

Find leaked API keys before attackers do

Public GitHub and GitLab pushes, exposed .env files, .git directories served as static assets, SSH keys leaked in repos. Recognises 23 secret formats — AWS, GitHub PATs, Stripe, OpenAI, Anthropic, Slack, Twilio, JWTs — and surfaces them within hours of the push.

Exposure Scoring

Quantified risk scores per asset and group with logarithmic severity weighting. Track score changes over time with trend analysis.

Know the moment something new shows up

A new subdomain, an open port that wasn't there last week, a service responding where one shouldn't. Checks run on a configurable cadence — every 12 hours to every 5 days — and alert rules fire only on the changes that matter, not every churn.

Remediation Workflow

Track findings through open → in progress → resolved. Accept risk with justification, suppress false positives, and measure time-to-remediate.

Reports & Trending

Generate executive summaries and full technical PDF reports with embedded charts. Schedule weekly or monthly report delivery.

Integrations

Connect to Slack, Jira, PagerDuty, email, and custom webhooks. Create notification rules that auto-fire on critical findings or exposure thresholds.

API & Automation

Full REST API with scoped API keys. Automate asset onboarding, trigger scans, pull findings, and integrate with your existing security toolchain.

Query your attack surface from any AI tool or LLM client

Connect any MCP-compatible AI tool or LLM client directly to your org's live attack surface data. Ask about findings, assets, scan history, and exposure stats without leaving your AI workflow.

Spot the domain pretending to be you

Typosquats, homoglyphs, IDN punycode tricks, TLD swaps, and look-alike domains built for phishing or brand impersonation. Continuous monitoring flags new registrations before they go live in a campaign.

Team & governance

Want to see exactly what we detect?

Every alert falls into one of seven categories — vulnerabilities, service exposure, leaked secrets & configs, misconfigurations, security hygiene, lookalike domains, and compromised credentials. Toggle any of them on or off, per organisation or per asset group.

How it works

Four steps to better external visibility

01

Discover

Add a root domain. We enumerate subdomains, IPs, services, and certificates across your entire external surface.

02

Scan & Score

Run automated scans with multiple engines. Every finding is categorized, scored, and enriched with remediation guidance.

03

Monitor & Alert

Set up continuous monitors with configurable frequency. Get alerts in Slack, PagerDuty, Jira, or email when things change.

04

Remediate & Report

Track findings through your workflow. Generate PDF reports for stakeholders. Watch your exposure score drop over time.

Continuous exposure

From EASM to CTEM

Continuous Threat Exposure Management is about continuously understanding what is exposed, what changed, what matters most, and what needs to be fixed first. Nano EASM focuses on the external attack surface layer of that journey — helping teams discover internet-facing assets, monitor exposure changes, prioritise findings, and mobilise remediation.

01

Discover

Uncover internet-facing domains, IPs, services, and cloud assets.

02

Prioritise

Rank findings by severity, exposure, and context.

03

Monitor

Track exposure changes over time.

04

Remediate

Turn findings into plain-English next steps.

05

Validate

Re-check fixes and confirm exposure reduction where supported.

Nano EASM focuses on the external exposure layer of CTEM — where unknown internet-facing assets, exposed services, and changing risk often create the first gaps teams need to close.
