acme-startup.com Needs attention
Scanned just now
HIGH
Verified
No DMARC record. Spoofed emails go through

No DMARC record found. Any email server can send emails pretending to be from your domain.

MEDIUM
Missing Content-Security-Policy

No Content-Security-Policy header. The browser has no restrictions on script sources, making XSS attacks easier.

MEDIUM
Missing clickjacking protection

No X-Frame-Options header and no CSP frame-ancestors directive. The page can be embedded in an iframe for clickjacking.

42 checks passed

You'll know what to fix by the time you finish your coffee.

Every check is deterministic and backed by evidence. No false positives. Each finding comes with business impact and a fix guide. You read it and know what to do next.

No config files. No scan policies. No onboarding calls. You type a domain and get a report.

Type your domain above and sign up. Your scan starts right after, no credit card needed.

Updated when new exploits hit, not on a release schedule

When a new zero-day drops, we test your app for it automatically.

When a new vulnerability hits the news, you don't have to wonder "does this affect me?"
We've already added the check and run it against your app.

Forged Email / Brand Impersonation

Exploitable

Anyone can send emails pretending to be from your domain.

Prerequisites (2)
Email is active Confirmed
SPF absent or permissive Confirmed
What we found (this finding)
DMARC absent
Attack technique
Send spoofed emails as your domain
Worst case
Phishing, brand damage, BEC fraud

Tap any step to see details

Findings connect into attack chains.

SPF and DMARC are both missing on this domain. Each one looks minor on its own. Together, anyone can send emails as your-company.com. That's phishing, brand damage, and BEC fraud from two missing DNS records.

Every finding with an attack path gets this diagram. You see exactly what's possible and why.

Tests what's behind the login, too

Your app has a login page. We test both sides.

Warden logs into your app with the credentials you supply and compares what each side of the login can reach: API endpoints that return data without authentication, admin and debug surfaces. It also checks CORS settings on authenticated API endpoints.

Set up takes two minutes. Add test credentials, Warden handles the rest. Requires the Warden plan.

The same tools a security researcher would use

AI pentesting that proves what's exploitable.

Our AI pentest dispatches parallel sub-agents with real security tools: sqlmap, ffuf, nuclei, Playwright. They navigate your app, test your login flows, probe your API, and chain vulnerabilities together.

Every finding goes through a 6-step deterministic validation pipeline. If it can't be proven, it doesn't get reported.

A pentest engagement costs €10-25K and goes stale in weeks. This is Focused €50, Standard €150 or Deep €400, run whenever you ship. You choose what the agent may touch and how long it may work — a bigger scope doesn't cost more. Any plan can start one, including an expired trial.

This is the report. Made for whoever is asking.

A customer sends a questionnaire. Your insurer wants proof of scanning. Your auditor wants SOC 2 evidence. Each one wants a different document, and you get all of them from the same scans.

Pick the standard they care about, SOC 2, ISO 27001, HIPAA or PCI DSS (supporting evidence, not an ASV scan), hit download, and send it. Dated, with the evidence behind every line. If you use Vanta or Drata, it lands there on its own.

Included with Warden. What SOC 2 auditors ask for.

If the report doesn't cover what your auditor asks for, tell me. I'll add it.

"I tested it on two domains and found the tool very intuitive and effective for quickly identifying low-hanging-fruit issues. It looks especially useful when applied the way you described in your post: making it accessible even for non-security folks."

Common questions

AttackerView is a website vulnerability scanner for startups. It tests your web app the way attackers do, proves every finding, and runs AI pentests.

No. Scans are non-destructive. We test for real vulnerabilities - exposed secrets, known CVEs, injection points, misconfigurations - but we don't modify data or overload your server. Authenticated scans on Warden test more deeply (API endpoints that answer without a login, admin and debug surfaces, CORS settings on authenticated API endpoints) with request volumes similar to a thorough visitor. AI pentests send crafted requests to prove exploitability. Read only is the default; if you answer yes to 'Can the agent change data?', it may create, change, or delete data as the selected account on the verified host and its subdomains, except off-limits paths. Use Off-limits for paths the run must not touch. Your answer controls whether it may send POST, PUT, PATCH and DELETE requests and open WebSocket connections. A GET request that changes data on your site is still sent in read only.

Everything an attacker would look at before trying to break in: whether your connections are secure, whether someone could impersonate your email, whether you're running software with known bugs, and more. Each finding comes with proof and a fix guide.

A security researcher who got tired of tools that generate noise instead of answers. Every check we run exists because it caught something real on a real app.

Because the product speaks for itself. You scan, you see the results, you decide if daily monitoring, alerts, compliance, and deeper checks are worth paying for. Evidence and fix steps unlock once you verify you own the domain. After 14 days, scans pause until you pick a plan, and the trial's scan data is deleted 7 days later.

Three things. First, every finding comes with proof - the exact HTTP response, DNS record, or certificate that proves the vulnerability exists. Second, we test behind your login page. Warden logs in with real credentials and compares both sides of it - checking whether API endpoints return data without a login, probing common admin and debug surfaces with and without a session, and testing CORS settings on authenticated API endpoints. Third, our AI pentests run real security tools (sqlmap, ffuf, nuclei, Playwright) across the application surface in parallel and validate every finding through a 6-step deterministic pipeline.

You buy one run and choose how long it may work: Focused €50, Standard €150 or Deep €400 plus applicable VAT. The size sets the maximum time and the price; if the agent finishes early, every full 6 minutes left on its clock comes back as a credit. Scope text guides the agent. Read only is the default; you can allow the agent to change data, with the test's off-limits paths always excluded. Any plan can buy a run, including an expired trial, and Hunter includes 20 credits a month. If it is blocked before it starts, tests nothing, or our service fails, we refund your card payment in full and return the credits it used; if it tests anything and then uses up its time, hits its cost limit, or is stopped, the run is delivered and charged. Credits stay on your account and never expire, but they are not a cash refund. Your answer to 'Can the agent change data?' controls whether it may send POST, PUT, PATCH and DELETE requests and open WebSocket connections. A GET request that changes data on your site is still sent in read only.
