Stop shipping client sites with visible security gaps.
Scan, fix, and prove it before handoff.
Pentestr gives web agencies, dev shops, and MSPs an automated external security check for every client site: SSL/TLS, security headers, WAF, exposed services, email security, and Nuclei findings. Get an A-F grade, remediation steps, and a report your client can understand in under 5 minutes.
Your clients assume their site is secure. You need proof before they ask.
For agencies and MSPs, one obvious security miss can turn a profitable client relationship into emergency unpaid work.
You manage too many client properties to check by hand
SSL, headers, exposed ports, WAF, DNS, and common CVEs are easy to forget when every client site has a different stack, deadline, and maintenance budget.
Clients want answers faster than security tools are set up
When a client asks if a launch is safe, you need a clear external check now, not a custom spreadsheet of scanner output later.
The painful part is proving the work was done
A raw terminal scan does not reassure non-technical clients. A graded report with concrete fixes gives your team and your client the same source of truth.
A repeatable security check for every client site.
Paste a client URL
Run a pre-launch, post-migration, or monthly maintenance scan without installing a security stack.
Check the public attack surface
Advanced SSL/TLS, security headers, WAF, tech fingerprinting, exposed ports, SPF/DKIM/DMARC, and Nuclei CVE templates.
Fix and send proof
Give your team a prioritized fix list and your client a simple A-F grade with concrete remediation.
The obvious security gaps clients still expect you to catch.
Pentestr focuses on the public issues that hurt trust, trigger urgent support, and should never survive launch.
Pre-launch TLS verification
Catch expired certificates, weak protocols, risky ciphers, and TLS issues before the client receives the final handoff.
Security headers your team can fix fast
HSTS, CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy, and other missing headers grouped into a clear remediation list.
WAF proof for client infrastructure
Detect Cloudflare, Akamai, AWS WAF, Imperva, and 150+ providers so your team knows whether protection is actually active.
Exposed services after migrations
Find risky internet-facing services after hosting moves, DNS changes, staging mistakes, and rushed production launches.
Email spoofing checks for client domains
SPF, DKIM, and DMARC checks help agencies spot domains that can be abused for phishing or customer fraud.
Stack exposure snapshot
Show frameworks, CMS, servers, and public fingerprints that attackers and client security reviewers can see from the outside.
CVE and misconfiguration scanning
Run Nuclei templates against public surfaces to catch known issues without maintaining a scanner setup for each client.
Simple grade for non-technical clients
Turn findings into an A-F grade, severity counts, and next actions that account managers, developers, and clients can discuss.
Not a pentest replacement. A client-site security workflow.
| Criteria | Pentestr | Manual pentest |
|---|---|---|
| Best use case | Launch, handoff, maintenance | Compliance or deep testing |
| Time to proof | < 5 minutes | Days to weeks |
| Per-client repeatability | ✓ Unlimited on Team | ✗ Scoped per engagement |
| Client-friendly grade | ✓ A-F + fixes | Often long technical PDF |
| External exposure checks | ✓ Built in | Depends on scope |
| Manual business logic testing | ✗ Automated scan | ✓ Human tester |
| Compliance certification | ✗ Not a certification | ✓ When contracted |
Use Pentestr before launch, after migrations, and during monthly care plans. Use a manual pentest when a client needs deep business-logic testing or formal compliance evidence.
Security workflows for teams managing client websites.
Built for one-off checks and recurring client care.
Start with credits for a launch. Move to Team when security checks become part of every client retainer.

Frequently asked questions
Would this client site earn an A grade?
Run the scan before launch, after migration, or before your next client review. Find the public gaps while your team can still fix them quietly.
