Audit Your TLS Configuration Before Attackers Exploit It

Weak ciphers, expired certificates, and outdated protocol versions create real attack opportunities. BEAST, POODLE, Heartbleed, and ROBOT are not theoretical - they are actively exploited. Our SSL/TLS Scanner performs a thorough analysis of your encryption configuration and tells you exactly what to fix.

How It Works

From target input to actionable findings in three straightforward steps.

01

Enter a Hostname and Port

Provide the target hostname (e.g., example.com) and port (defaults to 443). The scanner handles SNI automatically for hosts serving multiple certificates.

02

Deep Protocol Analysis

The engine tests every supported protocol version (SSLv3 through TLS 1.3), enumerates all accepted cipher suites, evaluates certificate chain validity, and checks for known vulnerabilities.

03

Receive a Graded Report

Get an overall security grade along with detailed findings for each issue. Every recommendation includes the specific configuration change needed for your web server.

Key Capabilities

Purpose-built scanning backed by real penetration testing expertise.

Protocol Version Testing

Tests support for SSLv3, TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3. Flags deprecated protocols that should be disabled to meet modern security standards.

Cipher Suite Enumeration

Lists every accepted cipher suite in preference order and flags weak algorithms including RC4, DES, 3DES, and export-grade ciphers.

Certificate Chain Validation

Verifies the full certificate chain from leaf to root, checking for expiration, revocation status, key strength, and trust chain completeness.

Known Vulnerability Checks

Tests for Heartbleed, POODLE, BEAST, ROBOT, CRIME, BREACH, DROWN, Logjam, FREAK, and other protocol-level attacks.

HSTS and HPKP Analysis

Evaluates HTTP Strict Transport Security headers and public key pinning policies to assess transport layer defense in depth.

Compliance Mapping

Maps findings against PCI DSS, NIST SP 800-52, and HIPAA requirements so you know exactly which compliance gaps exist.

Common Use Cases

Validate TLS configuration after web server deployments or certificate renewals to prevent outages and misconfigurations
Prepare for PCI DSS audits by verifying that deprecated protocols and weak ciphers are fully disabled
Monitor certificate expiration dates across your entire domain portfolio to prevent unexpected browser warnings
Verify that load balancers and CDN edge servers enforce the same cipher policy as your origin servers
Detect man-in-the-middle risk by confirming certificate chain integrity and proper HSTS deployment
Audit third-party SaaS providers and vendor portals to ensure they meet your organization security requirements

Why Use Pentestas

Security tools built by penetration testers, not just developers.

Enterprise-Grade Accuracy

Our scanning engine is built on the same methodologies our penetration testers use in manual engagements, tuned to minimize false positives and surface genuine risk.

Fast, Actionable Results

Get findings in minutes rather than days. Every result includes severity ratings, technical evidence, and clear remediation steps your team can act on immediately.

Continuous Monitoring

Schedule recurring scans from the Pentestas platform to catch regressions before they reach production. Stay ahead of new CVEs and configuration drift.

Privacy First

Your scan data is encrypted at rest and in transit. You own your data, with full control over retention and export.

Detailed Reporting

Export findings as PDF, CSV, or JSON. Feed results directly into your SIEM, ticketing system, or CI/CD pipeline through our REST API.

Instant Setup

Run scans directly from your browser. Enter a target, click scan, and receive results. Ready in under a minute.

Frequently Asked Questions

What vulnerabilities does the scanner check for?
The scanner tests for all major TLS/SSL vulnerabilities including Heartbleed (CVE-2014-0160), POODLE (CVE-2014-3566), BEAST, ROBOT, CRIME, BREACH, DROWN, Logjam, FREAK, and Sweet32. Each detected vulnerability includes its CVE reference and remediation steps.
Does it check certificate transparency?
Yes. The scanner verifies that certificates include Signed Certificate Timestamps (SCTs) as required by modern browsers, and cross-references certificate transparency logs to detect unauthorized certificate issuance.
Can I scan non-standard ports?
Absolutely. While the default is port 443, you can specify any port number. This is useful for scanning SMTP (465/587), IMAP (993), POP3 (995), and custom application ports using TLS.
How do I interpret the security grade?
The grade ranges from A+ (excellent) to F (critical issues). An A+ requires TLS 1.2 or higher only, strong ciphers, valid certificates, and HSTS. Any deprecated protocol or weak cipher immediately drops the grade. The report details every factor contributing to the score.
