Email spoofing protected DMARC, SPF, and DKIM configured correctly

Your attack surface is bigger than you think

Every exposed service, misconfigured setting, and forgotten subdomain is an entry point for attackers.

Automated scanners run 24/7

Bots continuously probe for exposed admin panels, outdated software, and misconfigured services. They find vulnerabilities within hours of appearing.

Pentests are expensive and slow

Professional security assessments cost $5,000-$50,000 and take weeks. You need continuous visibility, not annual snapshots.

You can't secure what you can't see

Shadow IT, forgotten subdomains, exposed APIs, debug endpoints. Most organizations don't know their full attack surface.

Attack surface analysis in 3 steps

No agents to install. No complex configuration. Just results.

Enter your domain

Add your domain and verify ownership with a simple DNS record or meta tag.

We scan everything

DNS, SSL/TLS, headers, exposed services, email security, and 20+ attack vectors.

Get actionable results

Prioritized findings with severity ratings and step-by-step remediation guides.

Comprehensive attack surface coverage

We test for real vulnerabilities that lead to breaches, not theoretical issues.

+ Email spoofing (SPF, DKIM, DMARC)

+ SSL/TLS configuration and certificate issues

+ Exposed admin panels and login pages

+ Security headers (CSP, HSTS, X-Frame-Options)

+ Sensitive file exposure (.env, .git, backups)

+ Subdomain enumeration and takeover risks

+ Outdated software and known CVEs

+ Open ports and unnecessary services

AI Security Advisor

How do I fix my DMARC policy?

Issue: Your DMARC policy is set to "none" which means email spoofing attempts aren't blocked.

Fix (5 minutes):
1. Log into your DNS provider
2. Find the existing _dmarc TXT record
3. Update the policy from p=none to p=quarantine
4. Your new record should be:
v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com

Frequently asked questions

Is this safe? Will it break my site?

SurfaceZero performs passive reconnaissance only. We don't attempt exploits or make changes to your systems. It's the same information an attacker could gather.

How do I verify domain ownership?

Add a simple TXT record to your DNS or a meta tag to your homepage. This ensures only authorized users can scan your domains.

What if I don't understand the results?

Every finding includes plain English explanations. Pro users can also ask our AI advisor to clarify anything or provide step-by-step remediation.

Can I use this for client sites?

Yes! Pro users get PDF reports perfect for sharing with clients. Many agencies and consultants use SurfaceZero for client security assessments.

How often are scans run?

Free users can run manual scans anytime. Pro users get automatic weekly scans with instant alerts when new vulnerabilities are detected.

What makes this different from other scanners?

We focus on attack surface reduction, not just vulnerability scanning. Plus our AI advisor actually helps you fix issues instead of just listing them.
