TLS Monitoring & Grading
Visibility into the Health and Trustworthiness of Your Encrypted Perimeter

Last Update il y a un an
Overview: As the backbone of secure communication on the modern web, TLS (Transport Layer Security) plays a critical role in ensuring the confidentiality, integrity, and authenticity of data exchanged between users and servers. But simply having a TLS certificate isn’t enough. Improper configurations, expired certificates, and misapplied best practices can leave encrypted channels vulnerable to exploitation—exposing organizations to downtime, MITM (man-in-the-middle) attacks, or reputational harm.
Our TLS Monitoring & Grading Service goes beyond simple certificate checks. We continuously scan, evaluate, and score your TLS endpoints based on their cryptographic health, operational hygiene, and conformance to modern security standards—including support for best practices like OCSP stapling, forward secrecy, strong cipher suites, and robust certificate chains.
By giving you real-time insight into your TLS posture—across domains, subdomains, and infrastructure—you gain the ability to anticipate failures, remediate risks, and demonstrate trustworthiness to users and third parties.
Why TLS Health Matters
TLS is not “set-and-forget.” Certificates expire, chains break, and configurations drift.
Misconfigured TLS can negate the benefits of encryption, allowing attackers to intercept or tamper with secure traffic.
Poorly implemented certificate status checking (OCSP) can introduce performance penalties, or worse—enable soft-fail attacks.
Search engines and browsers now penalize weak TLS deployments with warning labels, degrading user trust.
Key Features of Our TLS Monitoring & Grading Service
1. Certificate Lifecycle Monitoring
We continuously monitor your public TLS certificates for:
Expiration status (with early alerts for renewals)
Mismatched hostname/SAN entries
Self-signed or invalid certs
Incomplete or misordered certificate chains
Revocation status via OCSP and CRLs
This allows you to proactively address misconfigurations and avoid disruptive outages caused by expired or improperly deployed certificates.
2. OCSP Stapling Analysis
OCSP (Online Certificate Status Protocol) is the mechanism used by clients (like browsers) to check whether a TLS certificate has been revoked. Without OCSP stapling, every client must reach out to the certificate authority (CA) directly—slowing down the connection and introducing privacy and availability issues.
Why this matters
OCSP stapling allows the server to “staple” a valid OCSP response to the TLS handshake, drastically improving both performance and trust. Without it, users may experience delays—or worse, silently trust revoked certificates.
Our grading system evaluates not only whether OCSP stapling is enabled, but also whether it's functioning correctly and using recent, verifiable responses.
3. Cipher Suite and Protocol Analysis
We analyze your TLS configuration for:
Support for deprecated protocols (e.g., TLS 1.0, 1.1)
Use of weak cipher suites (e.g., RC4, 3DES)
Proper enforcement of forward secrecy
Preference for strong, modern algorithms (e.g., AES-GCM, ChaCha20, ECDHE)
Every endpoint receives a graded security score, helping your security and infrastructure teams identify where TLS hardening is needed.
We inspect your server’s presented trust chain for:
Root and intermediate CA validity
Trusted anchor consistency across major browsers
Chain ordering and duplication issues
Potential cross-signing or legacy trust issues
This ensures that clients—on mobile, desktop, or embedded platforms—can validate your TLS connections without failure.
Each monitored endpoint receives a TLS security score, taking into account:
Protocol strength
Key size and algorithm
Certificate trust and validity
OCSP stapling support
Cipher suite configuration
Handshake behavior and compatibility
Misconfigured encryption gives a false sense of security—and attackers know it. Whether it's a forgotten certificate, a revoked intermediate, or a TLS 1.0 server still lurking in your infrastructure, your encrypted perimeter is only as strong as its weakest handshake.
Our TLS Monitoring & Grading Service provides full-spectrum visibility into the state of your certificates and cryptographic posture—so you can build trust, avoid surprises, and stay ahead of evolving threats.
