SSL/TLS & Certificate Management

An expired certificate is one of the most common and most avoidable causes of downtime. The site throws a browser warning, customers bounce, the API stops trusting its partner, and everyone scrambles to find who owned that certificate and where it lived. The fix is boring and effective: a complete inventory, monitoring that alerts weeks ahead, and automated renewal wherever the platform supports it. SSL TLS certificate lifecycle management exists precisely so that Friday-night scramble never happens.

Most organisations have more certificates than they can list. Ones issued by a team that has since moved on, self-signed certs on internal services, certificates on cloud load balancers nobody tracks. Each is a potential outage or a security gap. Discovery is the unglamorous first step that makes everything else possible, because you cannot manage what you have never counted.

We scan your external footprint and, where you want, your internal networks to build a full inventory: every certificate, its issuer, expiry, key strength and where it is deployed. That inventory becomes the single source of truth, and it usually turns up several certificates the team had entirely forgotten.

Every certificate gets expiry monitoring with alerts well ahead of the deadline, so there is always time to act. Wherever the platform allows it, we automate renewal through ACME, using Let’s Encrypt or your chosen certificate authority, so short-lived certificates rotate themselves without anyone lifting a finger. For the certificates that cannot be automated, the monitoring and a clear owner keep them safe.

Certificate validity periods keep getting shorter across the industry, which makes manual renewal increasingly unworkable. Automation is no longer a nice-to-have; it is the only sustainable answer when certificates renew every few weeks. We set up that automation so the trend works for you instead of multiplying your renewal workload.

Key rotation and private PKI

For internal services, device identity and service-to-service authentication, you may need your own private certificate authority. We help you stand up and run a private PKI with sensible key rotation, so internal trust is managed as carefully as your public-facing certificates rather than left to a pile of expiring self-signed certs.

Many certificate outages are really ownership failures: the person who bought it left, and nobody inherited the responsibility. Our inventory records an owner and a renewal path for every certificate, so when someone moves on the certificate does not become an orphan waiting to expire. It is a small governance step that quietly prevents a large share of the incidents we get called about.

We disable the obsolete protocols, TLS 1.0 and 1.1 and anything older, which are deprecated and flagged by every scanner and auditor. We enforce TLS 1.2 and 1.3, remove weak cipher suites, and configure forward secrecy so a compromised key cannot decrypt past traffic. These changes are usually invisible to users and decisive on a security report, and they are among the first things a penetration test or a customer security questionnaire will check.

HTTP Strict Transport Security tells browsers to only ever connect over HTTPS, closing the window where a user could be downgraded to an unencrypted connection. We configure it correctly, including the preload considerations, so the enforcement is real rather than cosmetic.

Choosing between a wildcard certificate covering all subdomains and a multi-domain SAN certificate is a trade-off between convenience and blast radius. A single wildcard key that leaks exposes every subdomain at once. We help you pick the structure that balances manageability against risk for your estate rather than defaulting to whatever is easiest to buy.

We watch the CT logs for certificates issued for your domains. A certificate you did not request appearing in the logs can be an early sign of a mis-issuance, a compromised registrar, or an attacker preparing to impersonate you. Catching it early lets you get it revoked before it is used against your customers.

When a key is compromised or a certificate must be pulled, speed matters. We manage revocation and rapid reissuance, and if the situation points to a wider compromise, our incident response team steps in to understand how the key was exposed and to close the path.

When we harden your TLS, we verify it the way we would attack it: checking for downgrade paths, weak ciphers that a scanner missed, misconfigured certificate chains, and internal services quietly running deprecated protocols. A clean external grade can still hide a soft internal endpoint, and we look for exactly that.

Certificates touch identity, encryption and trust, so we manage them as part of your wider posture rather than in isolation. The certify SSL TLS certificate management work connects to your monitoring, your incident response and your compliance evidence, so it is one coherent control instead of a standalone spreadsheet.

Encryption in transit is required across PCI DSS, ISO 27001, GDPR and DORA. We document the TLS configuration and certificate governance so an auditor gets clear evidence, and so the next penetration test does not waste time flagging the same deprecated protocols.
