The drastic reduction in the lifecycle of TLS certificates is about to irreversibly transform IT management. What was once an annual or semi-annual task will soon become an almost daily activity. According to Andrés Mendoza, Technical Director for Southern Europe and Latin America at ManageEngine, a division of Zoho Corporation, this structural change will force IT teams to renew certificates up to eight times a year, multiplying the operational load and increasing the risk of human error.

A Structural Change Redefining Daily Operations

Mendoza does not hesitate to describe this transformation as a structural change. "Certificate management will cease to be a periodic task and become an almost continuous operational activity," he states. Each renewal involves a complete process: sending the certificate to the server, executing scripts, restarting dependent services, and validating that everything works correctly. With cycles going from 200 days in 2026 to 100 days in March 2027 and finally to 47 days in March 2029, the frequency skyrockets.

The impact is already visible in real organizations. RevSpring, a US healthcare provider, has gone from managing fewer than 200 certificates to over 2,000. "This requires dedicating a considerable amount of engineering effort just to this task," Mendoza notes. Failures are not minor: a late renewal or incorrect deployment can disrupt critical services, as happened with Microsoft Teams in 2020, when a seemingly trivial failure affected millions of users.

"Maintaining manual processes will turn certificate management into an operational bottleneck that compromises the continuity of digital services," warns Mendoza. For companies that have not yet automated, the scenario is alarming. As mentioned in our article on how IT teams drown in cloud security findings, operational overload is a recurring symptom in environments without automation.

False Sense of Security: Partial Automation Is Not Enough

Although many providers promise automatic renewal, the critical phase—final deployment—remains manual in most environments. "Automating only renewal does not solve the problem. A renewed certificate protects nothing until it is correctly deployed and goes into production," explains Mendoza. It is in this phase where failure points concentrate: a pending restart, an unexecuted script, or a skipped validation can leave the previous certificate operational. "In practical terms, a renewed certificate that is not correctly deployed is equivalent to an expired certificate," he continues.

Maintaining a hybrid flow increases risk as cycles shorten. "Each repetition of the process is a new opportunity for human error," he points out. Therefore, he insists that automation must be complete: detection, renewal, deployment, and validation. "Only end-to-end automation eliminates the last point of human failure and turns the entire cycle into a truly automatic process," he adds. To address this challenge, ManageEngine offers Key Manager Plus (KMP), which automates post-renewal tasks and allows the complete flow to run without manual intervention.

This need for comprehensive automation echoes the efficiency principles applied in advanced home automation with Home Assistant, where automated coordination of multiple systems eliminates bottlenecks and manual errors.

The Cost of an Expired Certificate: Beyond the Outage

The impact of an expired or incorrectly deployed certificate is immediate. "An invalid certificate blocks secure access and forces activation of emergency procedures," explains Mendoza. In sectors such as payments, healthcare, public administration, or business services, these incidents can paralyze essential processes. Added to this is the operational cost, as each failure diverts resources from strategic tasks to resolving avoidable incidents. "It is an opportunity cost that affects productivity and the ability to advance key projects," he notes. "Furthermore, reputation and user trust are affected, compromising business continuity."

That is why he insists that certificate management should be considered "an essential component of operational resilience, not an administrative task." This strategic approach is similar to that addressed in ransomware governance, where prevention and automation are key to preventing a small failure from paralyzing the entire organization.

Shorter Cycles: The Path to Full Automation

Faced with increasingly shorter renewal cycles, organizations must completely review their processes. Mendoza estimates that "the first step is to know precisely the certificate inventory." Without a clear inventory, it is impossible to size the risk or anticipate the impact of moving to 100- or 47-day cycles. The next step is to automate the entire cycle. "Any manual phase becomes a failure point when the renewal pace accelerates," he explains. ManageEngine has launched a 47-day TLS impact calculator that allows estimating the current operational load and visualizing how exposure to outages is reduced through automation.

Finally, he recommends adopting a certificate authority-independent approach. "Modern environments combine multiple CAs, servers, and applications. If each is managed in isolation, complexity grows and the probability of error increases," he warns. Centralizing management avoids these silos and allows operating coherently in hybrid and multicloud environments. This centralization principle also applies in energy and telecommunications management, where a unified dashboard reduces complexity and improves control.

Mendoza recommends integrating this approach into a broader machine identity management strategy. "TLS certificates are just one piece of the ecosystem. SSH keys, Azure secrets, and other credentials form a set that must be managed in a unified manner," he explains. Consolidating these identities from a single place improves visibility, reduces errors, and allows scaling operations without increasing manual load. ManageEngine's proposal is based on this model: complete automation of the certificate lifecycle and centralized management of all machine identities. "It is an approach that turns certificate management into a reliable and scalable process, and positions machine identity as a strategic requirement to ensure security, continuity, and operational efficiency," he concludes.

For companies looking to optimize their CRM and reporting, automating critical processes like certificate management can be integrated into dashboards such as those described in Reports and Core CRM, offering a unified view of operational health.
