Who Intruder is really for
Intruder is a capable, well-established platform. Its strengths are genuine: continuous vulnerability scanning with strong emerging-threat coverage, a polished interface, and mature integrations with tools like Jira, Slack, and cloud connectors. Technical security teams at growing mid-market companies get real value from it.
The friction for smaller organisations is pricing. As of September 2026 (re-verified against Intruder’s public pricing page), paid plans start around $299/mo for Cloud and $499/mo for Pro (about $399/mo billed annually) — the older ~$99/mo Essential tier no longer appears. Pricing works as a base fee plus a per-target licence, where each scanned target consumes a licence held for 30 days, so costs climb as your surface grows. The free plan is real but minimal: weekly external scans watching ports 80 and 443 only. Some smaller customers report price increases and note it is “not startup-friendly.”
Who SurfaceLoop is for
SurfaceLoop is built for businesses up to around 200 employees that want visibility without needing a dedicated security team. Automated asset discovery is included as standard, so you find the assets you forgot about, not just the ones you list. Pricing is one published flat price — £149/mo on a 12-month agreement, billed by invoice — with no per-target licence maths, and every finding comes with plain-English remediation rather than raw scanner output.
How SurfaceLoop handles this
SurfaceLoop discovers your internet-facing assets from a single root domain and monitors them continuously. Start a 14-day free trial of the full product on your own domains — no card details, no sales call.
See External Attack Surface Management feature →Which should you choose?
Choose Intruder if you have a technical security team, want deep integration into an existing workflow, and can justify per-target licensing as your estate grows. Choose SurfaceLoop if you are a smaller business that wants discovery-first monitoring included from the start, one flat price, plain-English fixes, and a free 14-day way to prove it on your own estate.

Frequently asked questions
- Is Intruder or SurfaceLoop cheaper for a small business? +
- It depends on your estate. As of September 2026 Intruder's paid plans start around $299/mo (Cloud, as reported on its public pricing page) and use a base fee plus a per-target licence -- a licence is used each time you scan a target and stays used for 30 days -- so costs rise with each target you scan. A limited free plan exists (weekly scans of ports 80 and 443 only). SurfaceLoop is one flat £149/mo with discovery and every scan category included, so the price doesn't move as your surface grows. An unknown or growing surface is more predictable on SurfaceLoop.
- Does Intruder include external attack surface discovery? +
- Yes -- Intruder's current plans present attack-surface discovery features across tiers, and its free plan offers weekly external scans limited to ports 80 and 443. The practical difference is packaging: fuller coverage sits on paid tiers with per-target licensing, while SurfaceLoop includes automated discovery and all seven scan categories as standard on one flat-price plan.
- Do I need a credit card to try either tool? +
- Intruder offers a 14-day free trial; its pricing page does not state whether a card is required. SurfaceLoop's 14-day trial requires no card at all -- and no sales call either: you start online and run the full product on your own domains. If you continue, billing is by invoice -- there is never a card on file.
- How much does Intruder actually cost? +
- As of September 2026, as reported on Intruder's public pricing page: a limited free plan (weekly external scans of ports 80 and 443), Cloud from around $299/mo, Pro from around $499/mo (roughly $399/mo billed annually), and custom Enterprise pricing, with annual billing discounted by about 20%. On top of the base fee, a per-target licence is consumed each time a target is scanned and stays used for 30 days -- so the real monthly cost depends on how many targets you scan.
- Is Intruder a bad product? +
- No. Intruder is a mature, well-integrated vulnerability scanner with strong emerging-threat coverage and a large customer base, and it suits technical security teams at growing mid-market companies. It is simply priced and packaged for a different buyer than a small business wanting affordable, discovery-first monitoring.
