What security should a small business start with? External attack surface management — then pick managed or DIY.
Short answer first. Then use the questions below to pick a managed provider tier or a DIY path. No quiz software — jump links only. Rankings use our published methodology.
External attack surface management is continuous external exposure monitoring: it shows what is internet-facing (domains, IPs, subdomains, ports, services) and alerts you when that picture changes. For most founders and small teams without a security department, this is the practical first step — before a full tool stack, a pentest program, or enterprise platforms.
EASM helps you see exposure and change. It does not guarantee breach prevention or compliance by itself.
Match tools to how much you actually expose — not to enterprise marketing tiers.
A handful of public services. Payments usually through Stripe, Square, or PayPal. You mainly need to know when something new appears or an old service becomes risky.
Path: Entry-level managed EASM with scheduled scans and clear change alerts.
Growing cloud and on-prem footprint, customer data or IP to protect, more chance of forgotten assets. EASM plus occasional vulnerability scanning is usually enough without compliance mandates.
Path: Small-business managed EASM comparisons.
You need integrations, reporting cadence, and often a clearer compliance story. SMB-first tools may still help for external visibility, but expectations rise.
Path: Medium-business guidance; enterprise only if you have dedicated security staff and complex scope.
Stay with lightweight external attack surface management. Focus on discovery, scheduled monitoring, readable alerts, and published pricing.
EASM is still a sensible foundation (prove you know what is exposed and that you monitor change), but your floor often rises: stronger reporting, integrations, and sometimes broader testing. Pure SMB-only tools may not be the best primary fit.
ScanReview does not certify compliance. Use specialist guidance for regulated programs.
Start with EASM so you know every internet-facing hostname, port, and service. Add web-focused scanning when the surface is visible and stable.
External exposure is still the first blind spot attackers probe. Use managed EASM plus vulnerability scanning; keep access control and backups in your normal ops stack.
External-only EASM is not enough as your primary control if the risk is inside the LAN. You may still want external monitoring for VPN edges, admin portals, and cloud ingress — then look at tools with internal scanning or a specialist.
If a vendor is external-only, we say so on the comparison pages.
Use open-source reconnaissance and scanning tools to map the attack surface yourself. Plan time for install, scheduling, false positives, and follow-up — the tools are free; the process is not.
When alerts and consistency matter more than tool cost, move to managed EASM.
Pick a managed external attack surface management provider with published pricing and self-serve signup. Entry level for a few assets; small business when the footprint grows.
You may still use EASM concepts, but product fit shifts toward platforms with integrations, enterprise support, and broader programs. Do not force an SMB tool into an enterprise job.
