The 5 Best EASM Tools for Small Businesses in 2026
How we compared them
First, a declaration: SurfaceLoop is our product. We have put it first in this guide, said why we think it wins for small businesses, and given every competitor a fair hearing with their genuine strengths stated plainly. Judge our bias against the facts below — every price is dated, attributed as reported, and checkable against the vendor’s own pages.
We compared each tool on five criteria that matter most when a small business is buying:
- Entry price and pricing model — not just the headline number, but how the bill moves as your estate or team grows.
- Discovery at the entry tier — whether the plan you would actually buy includes automated asset discovery, or only scans targets you already know about.
- Trial terms — length, whether a card is required, and whether you get the full product or a cut-down demo.
- Who it is built for — every tool here is good for someone; the question is whether that someone is you.
- Plain-English vs technical output — whether findings can be actioned by a generalist IT person, or assume a security specialist is reading.
All competitor prices below are as of September 2026, as reported on the vendors’ public pages.
SurfaceLoop — best for small businesses without a security team
SurfaceLoop is our product, so read this section with that in mind — the facts are checkable on our pricing page and in a free trial.
SurfaceLoop is one flat price: £149/mo, all-inclusive, on a 12-month agreement invoiced by AMVIA — there is never a card on file. Automated asset discovery is included as standard, and every discovered asset is monitored across seven scan categories, with change tracking and alerts by email, Slack, or webhook, plus an API. Findings arrive as plain-English, prioritised guidance rather than raw scanner output, which is the point: SurfaceLoop is built for businesses up to around 200 employees that do not have a dedicated security team.
The trial is 14 days of the full product on your own domains — no card, no sales call.
Where SurfaceLoop is not the best fit: if you need deep authenticated application scanning, a vendor-risk platform, or per-asset billing granularity, one of the tools below will serve you better.
How SurfaceLoop handles this
SurfaceLoop discovers your internet-facing assets from a single root domain and monitors them continuously across seven scan categories. 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 →Attaxion — best for defined asset estates wanting per-asset pricing
Attaxion is the closest thing to a direct rival in this list: discovery-first, transparently priced per asset, and clean to buy self-serve. As of September 2026, as reported, its tiers are Starter at $129/mo (40 assets), Plus at $349/mo (120 assets), and Business at $949/mo (360 assets). The 30-day all-features trial is the most generous here, and after it ends there is a free Community Edition — monthly scans of up to 40 assets, though only 50% of findings are viewable on the free tier.
The caveat is how per-asset tiers behave when discovery does its job. Your 41st discovered asset moves you from $129/mo to $349/mo — so a tool whose purpose is finding assets you forgot about can make its own success expensive. And a free tier that hides half its findings is a teaser rather than ongoing monitoring.
Attaxion genuinely wins for a business with a well-defined, stable asset count that values per-asset pricing granularity and wants a full month to evaluate. See our detailed SurfaceLoop vs Attaxion comparison and our guide to the best Attaxion alternative.
Intruder — best for technical teams wanting mature vulnerability scanning
Intruder is a mature, well-integrated vulnerability scanning platform with a large customer base and strong integrations into tools like Jira and Slack. As of September 2026, as reported, there is a free plan (weekly scans, limited to ports 80 and 443), with paid plans from around $299/mo (Cloud) and around $499/mo for Pro (roughly $399/mo billed annually). Pricing works as a base fee plus a per-target licence, with a licence consumed per scan and held for 30 days. The trial runs 14 days.
Intruder’s output and workflow are oriented at technical teams — which is a strength if you have one and a friction point if you do not. The per-target licence model also means costs climb with the size of your scanned estate, which needs budgeting for as you grow.
Intruder genuinely wins for a technical security team that wants deep, mature vulnerability scanning wired into an existing workflow. See our detailed SurfaceLoop vs Intruder comparison and our guide to the best Intruder alternative.
Detectify — best for application security teams prioritising accuracy
Detectify’s edge is accuracy: scanning informed by ethical-hacker research, with low false-positive rates that application security teams value highly. If confirming real, exploitable weaknesses in web applications is your priority, it is an excellent tool.
The commercial shape is the small-business friction. As of September 2026, as reported, there is a free Starter tier, but paid platform fees start “from” €2,500/yr (Standard), €5,000/yr (Professional), and €15,000/yr (Enterprise) — plus per-domain and per-target usage charges on top. That “from” pricing is quote-shaped: the number you actually pay depends on a conversation, not a pricing page.
Detectify genuinely wins for an appsec team at a company that can budget four figures a year and up, wants research-driven accuracy, and has specialists to act on technical findings. See our detailed SurfaceLoop vs Detectify comparison and our guide to the best Detectify alternative.
UpGuard — best for organisations focused on vendor risk
UpGuard is a broader platform than the others here: alongside attack-surface features, its centre of gravity is security ratings and third-party/vendor risk management, aimed at the mid-market and enterprise. As of September 2026, as reported, its Breach Risk product is self-service from $250/mo, scaling by employee count up to around $2,000/mo; the broader vendor-risk and ratings platform is sales-led.
That headcount-scaled pricing is the thing to watch as a smaller company: your bill rises as you hire, even when your actual attack surface has not changed — a model that penalises growing teams.
UpGuard genuinely wins for an organisation whose real problem is assessing a portfolio of suppliers and vendors, not just monitoring its own estate. See our detailed SurfaceLoop vs UpGuard comparison and our guide to the best UpGuard alternative.

Which should you choose?
There is no single winner — there is a right tool per buyer:
- You run a business of up to ~200 employees with no security team. Choose SurfaceLoop: discovery included, one flat £149/mo that never moves with asset count or headcount, plain-English fixes, and a 14-day no-card trial to prove it on your own domains.
- You have a defined, stable asset count and want per-asset pricing granularity. Choose Attaxion — and use the 30-day trial to confirm your discovered asset count actually stays inside your tier.
- You have a technical security team and an existing workflow to integrate with. Choose Intruder for its mature vulnerability scanning and strong integrations, budgeting for per-target licences as your estate grows.
- You are an appsec team that prioritises scanning accuracy above all. Choose Detectify for its ethical-hacker-driven research and low false positives, and go in expecting quote-shaped pricing.
- Your real problem is vendor and third-party risk, not just your own estate. Choose UpGuard — it is the only tool here built around security ratings across a supplier portfolio.
Whichever way you lean, trial before you buy: the fastest way to compare EASM tools is to point two of them at your own domain and compare what they find.
Frequently asked questions
- What is the best EASM tool for a small business? +
- It depends on the business.

Attaxion suits defined asset estates, Intruder suits technical teams, Detectify suits application security teams, and UpGuard suits organisations focused on vendor risk.
- Which EASM tools offer a free tier or free trial? +
- As of September 2026, as reported: SurfaceLoop offers a 14-day full-product trial with no card. Attaxion offers a 30-day all-features trial, then a free Community Edition with monthly scans of up to 40 assets, though only half of findings are viewable. Intruder has a free plan limited to weekly scans of ports 80 and 443, plus a 14-day trial. Detectify has a free Starter tier.
- How much do EASM tools cost for a small business? +
- As of September 2026, as reported: SurfaceLoop is £149/mo flat. Attaxion starts at $129/mo for 40 assets, rising to $349/mo at 41 assets. Intruder's Cloud plan starts around $299/mo plus per-target licences. Detectify's paid platform fees start at €2,500/yr plus per-domain usage charges. UpGuard's Breach Risk runs $250 to $2,000/mo depending on employee count.
- Isn't SurfaceLoop biased, given this is its own roundup? +
- Yes -- SurfaceLoop wrote this guide, and we say so openly in it. Our defence is the method: every price is dated and attributed, every competitor's genuine strengths are stated plainly, and each verdict names the buyer that competitor wins for. Judge the bias against the facts, and check the vendor pages yourself.
- Do small businesses actually need an EASM tool? +
- If you have anything internet-facing beyond a single website -- staging sites, old subdomains, cloud services, email infrastructure -- then yes. Small businesses typically lack a security team to track what is exposed, which is exactly the gap EASM automates: discovering your internet-facing assets and monitoring them continuously for weaknesses.
- What should I check before choosing an EASM tool? +
- Five things: the entry price and how the pricing model scales (per asset, per target, per employee, or flat); whether asset discovery is included at the tier you would actually buy; the trial terms (length, card requirement, whether it is the full product); who the tool is built for; and whether findings are written for specialists or in plain English.
