Somewhere in your estate right now, a certificate is counting down to its expiry date. Today you probably know which one, because renewals still come around annually and someone owns the calendar. The industry is taking that comfort away: the CA/Browser Forum has voted to cut the maximum TLS certificate lifespan to 47 days by 2029, a decision we looked at in detail in our piece on shortened renewal periods. Renewals that happen once a year will soon happen every few weeks, and every manual touchpoint in that process becomes a potential outage. The math stops working.

The honest complication is that most enterprises do not live in a single-vendor world. You may run your own internal PKI. You may have standardized on a dedicated Certificate Lifecycle Management (CLM) platform. You may answer to compliance mandates that dictate exactly which Certificate Authority issues your certificates, and how. In those environments, visibility and control across every certificate matters as much as automating the renewals themselves. Until now, connecting those established workflows to Imperva meant manual effort, and manual effort is exactly what shrinking lifecycles no longer allow.

Today we are introducing the SSL Integration Center: an integration framework connecting Imperva Cloud WAF with leading Certificate Lifecycle Management platforms. It launches with its first supported integration, the DigiCert Trust Lifecycle Manager (TLM) Agent.

Your CLM stays in charge for certificate lifecycle management

The SSL Integration Center is not a new product or another console to learn. It is an integration framework, and the experience runs from the side you already live in: you configure the integration from within your CLM platform, and your CLM remains the place where certificates are managed. Once connected, two things happen from there. You can see all of your Imperva-managed domains and the SSL coverage status of each one, directly in your certificate workflow. And the complete certificate lifecycle cadence, issuance, renewal and deployment to Imperva, runs automatically under the policies your CLM already enforces. Imperva’s role is to integrate smoothly into the workflow you have, supplying application and SSL-coverage visibility and taking automated deployment off your hands. DigiCert is the first integration, and it sets the pattern for the CLM vendors that follow.

Thales-managed or customer-managed: your choice

Many organizations choose Thales-managed certificates because that removes the operational load of provisioning, renewal, monitoring and deployment in one move, and for them nothing changes. Others cannot adopt a fully managed approach: compliance requirements, PKI investments, established CLM platforms and governance policies often require a customer to keep control of their own certificate ecosystem. The Integration Center is built for that second group. You keep your CA, your CLM and your lifecycle processes, exactly where they run today, and Imperva plugs into them. Governance stays yours, and so does the console.

Starting with a leader: DigiCert Trust Lifecycle Manager

DigiCert TLM gives enterprises one place to discover, govern, automate and see certificates across cloud, hybrid and on-premises environments. It builds an organization-wide certificate inventory, enforces consistent cryptographic policy, and replaces surprise expirations with automated renewals. A useful way to think about the pairing: TLM is the system of record for your certificates, and the Integration Center is the delivery route into the applications Imperva protects.

With this integration, the DigiCert TLM Agent automates certificate issuance, renewal and deployment straight into Imperva. Under the hood, a post-enrollment script securely uploads the certificate chain and private key to Imperva through the Provisioning API, so a certificate governed in TLM arrives at your protected applications without anyone touching it. It runs on both Linux and Windows.

The value of that automation is documented. In a commissioned Total Economic Impact study, Forrester Consulting found organizations standardizing on DigiCert ONE, the platform behind Trust Lifecycle Manager, achieved 96% fewer outages from expired or misconfigured certificates, and a 312% return on investment over three years.

How the DigiCert TLM integration works

  • Govern in DigiCert TLM. Your certificate is issued and managed centrally, under the policies your organization already enforces.
  • Automate with the TLM Agent. A post-enrollment script runs on issuance or renewal and packages the certificate chain and private key.
  • Deploy through the Provisioning API. The script securely uploads the certificate to your Imperva cloud account and puts it to work protecting your applications. No manual upload. No missed renewal window.

What this means for your team

  • Continuous, compliant TLS protection. Issuance, renewal and deployment of custom certificates run without manual intervention, so your encryption stays current as lifecycles shrink.
  • Full bring-your-own-CA automation. If you use your own Certificate Authority and custom certificates, the entire lifecycle can now run end to end.
  • Fewer outages, less toil. Removing the manual steps removes the TLS outages that come from missed renewals, and frees your team from certificate babysitting.
  • Your Imperva estate, visible from your CLM. Once connected, your Imperva-managed domains and the SSL coverage status of each appear inside your certificate workflow, so DigiCert’s organisation-wide discovery and Imperva’s application coverage read as one picture, without switching consoles.

A certificate automation ecosystem that grows with you

Shorter certificate lifecycles are the new baseline, and they reward the organizations that automate. The SSL Integration Center makes that automation work on your terms: the CA you trust, the CLM platform you have standardized on, the compliance posture you are held to. It sits alongside Thales’s own SSL management capabilities, including certificate visibility, site coverage monitoring, notifications and real-time SSL health monitoring. DigiCert Trust Lifecycle Manager is the first integration and it will not be the last; each CLM vendor added becomes one more certificate workflow that arrives at your applications without a human in the renewal loop.

That certificate counting down in your estate? Under TLM and the Integration Center, its renewal has already happened by the time you would have thought to check.

It is also one thread in a wider fabric. Imperva integrates across the tools enterprises already run, from SIEM and ITSM platforms to API gateways, scanners and cloud providers, through the Imperva Technology Alliance Program. If your certificate stack is the workflow we meet today, the rest of your stack has a meeting point there too.
