SSL/TLS provides cryptography for securing connections to the internet, encrypting communications between the user’s browser and a web server, authenticating the web server’s identity with a digital certificate, and protecting the data from being read or altered while in transit.
Although “SSL” is still a commonly used name for the older protocol, SSL’s successor, TLS, is now the modern protocol used to support HTTPS.
So when you think of SSL/TLS today, think of SSL/TLS as more than just encryption; you should also consider the trust between users and servers and how SSL/TLS protects both parties’ identities during all digital transactions.
Websites without SSL are now treated as insecure by browsers, search engines, and users alike. HTTPS is mandatory for SEO visibility, browser trust indicators, API communication, and compliance with data protection regulations.
Many modern web features, such as HTTP/2, HTTP/3, service workers, and secure cookies, do not function without TLS.
The role of SSL has evolved beyond just an added measure of security; it’s now a baseline expectation for any digitally delivered product marketed to the public.
The trend in the Certificate Authority (CA) industry is to shorten the certificate lifetimes to reduce uncertainty and improve functionality by way of cryptographic agility.
By 2026, the longest-validity public TLS certificate will have a cycle of 200 days of allowed usage. Plans for even more reduced validities include 100-day cycles for 2027 and 47-day cycles by 2029.
As the certificate’s life gets shorter, the impact of any compromised keys would also be greatly reduced. Shorter certificate lifetimes would force organizations to adopt stronger algorithms sooner, as well as implement post-quantum cryptography.
But they would also require organizations that don’t have automatic certificate renewals in place to increase their number of renewals, which will create an increase in workload for organizations that rely on manual renewals.
Automation is the only viable method of operating secure digital services, given the severity of the risks accompanying the need for frequent renewal of SSL/TLS Certificates, as well as the future of secure communications technologies; organizations are required to rely on automated certificate management solutions.
Manual renewal will place organizations in the high-risk position of uncertainty around outages, misconfigured certificates, and potentially non-compliant certificates.
Automated Lifecycle Management (ALCM) is the easiest way for organizations to continuously discover, renew, deploy, and enforce policies to manage SSL/TLS across hybrid and Multi-Cloud environments.
Organizations that do not implement automated management for SSL/TLS Certificates will almost certainly find it to be impossible to continue providing uptime, security, and confidence at scale post-2025. Major trends in SSL/TLS are currently redefining the way people think about securing websites.
The management of SSL certificates is moving away from manually maintaining and renewing certs to completely automated processes. With decreased lifetimes and increased rates of renewing certs, it is no longer feasible for management to rely on humans for cert management.
Cloudflare demonstrates how a fully automated SSL/TLS solution can scan, validate, upgrade, and enforce encryption across millions of web domains without causing any interruption in service.
Automation minimizes the risk of certificate expiration, increases compliance with the CA/B Forum criteria, and ensures that the encryption is applied consistently as the Standards for Website Security evolve.
As automation has become an integral part of how SSL is managed at the internet scale, it has become the foundation for establishing reliable website security.
The replacement of older versions of TLS with TLS 1.3 is gaining significant traction across multiple industries because of its superior level of security and performance, and the removal of legacy cipher suites and/or reduction in the number of handshake round-trips.
TLS 1.3 can create a faster and more secure connection than its predecessors by default.
Experts across numerous industries attribute the fact that the majority of the encrypted traffic being transmitted is now done using TLS 1.3, while the number of transmissions using TLS 1.2 is dwindling, and the frequency of transmissions using TLS 1.0 and TLS 1.1 has all but ceased.
The changes happening within the SSL/TLS space are a reflection of the collective view of the industry that the most current and modern security measures for protecting the data of your clients and visitors on the internet.
These have to be focused on two primary elements of website security- a strong level of cryptographic protection and providing an improved user experience; TLS 1.3 provides a high degree of both without any sacrifice to either.
As CDNs mediate most web traffic, security focus has expanded beyond the browser-to-edge connection to include edge-to-origin encryption.
While front-end HTTPS has matured, backend connections historically lagged due to legacy servers, self-signed certificates, and inconsistent configurations.
Automated SSL/TLS upgrades are now closing this gap by enforcing HTTPS, strict certificate validation, and modern TLS between CDN edges and origin servers.
Strengthening edge-to-origin encryption reduces internal attack surfaces, protects sensitive data flows, and ensures end-to-end trust—making backend security just as critical as what users see in their browsers.
Website owners must now consider the evolving SSL/TLS landscape as fundamentally changing the way security is handled.
Due to shorter certificate lifetimes, renewals will happen multiple times per year, which makes tracking renewals manually impractical and risky.
A missed renewal can lead to outage, browser warnings, loss of user trust and revenue. Security is no longer something you can “set it and forget it,” as it requires oversight on an ongoing basis as well as reliable automated tools.
The evolution of the SSL/TLS landscape also increases the technical requirements for readiness.
Websites need to not only support modern TLS 1.3 protocols and maintain a clean certificate chain, but they need to ensure that their origin server configurations are configured to secure a connection behind a CDN/load balancer.
With the shift from front-end HTTPS encryption between the edge and origin, attackers are increasingly targeting internal traffic, and website owners must be aware of this and take measures to protect themselves from it.
Finally, website owners need to change their mindset from compliance-based SSL deployment to managing SSL certificates as part of a larger lifecycle-based approach to security management.
Investing in automated certificate lifecycle management, monitoring as well as quantum-resistant cryptography is no longer a choice; it is an obligation.
Early adopters will achieve stability, performance, and trust, while continuing delay poses a threat of operational disruption as the policies of the browser, the rules and regulations of the certificate authority and evolving cryptography standards continue to tighten.
SSL/TLS security relies heavily on automation as its main target. The use of an ACME-based renewal system or platform-managed SSL allows for automated certificate renewal without the need for human intervention, thereby decreasing the chances of an expired certificate causing a disruption in service.
The combination of proactive monitoring and alerting will provide insight into the overall health of certificates, allowing for any misconfigurations or issues to be addressed prior to affecting users.
With this adoption of automation, users can maintain ongoing security and reduce the need to allocate resources to performing standard routine maintenance tasks.
Using short-lived certificates will help secure your website by reducing the time frame a compromised certificate would have to provide access to your website. Viewing renewals as a routine scheduled occurrence will provide your website with up-to-date protection against various kinds of attacks.
Additionally, the constant rotation of encryption keys will provide for enhanced encryption as long-term exposure of private keys will not occur.
By using this forward-thinking approach, the practice of managing SSL certificates shifts from a reactive response to a proactive cycle of continuous website security, and allows your website to remain in compliance with the most up-to-date cryptographic standards.
Modern TLS protocol versions, especially TLS 1.3, provide improved speed and security over earlier protocols.
By removing support for older TLS 1.0 and 1.1, you remove the security vulnerabilities associated with these older protocols and allow for the use of the best cryptographic technologies available.
Validating the origin’s certificate strictly is an important means of protecting yourself against man-in-the-middle attacks and ensuring there is trust between the edge and origin servers.
Regularly updating TLS configurations is also a critical component of maintaining a strong security posture and providing optimal performance to your websites.
Early preparation is essential in order to avoid the risks associated with quantum computing on traditional cryptography, thus allowing organizations to implement hybrid TLSs that include both classical and PQC (Post-Quantum Cryptography) key agreement methods by tracking PQC vendor roadmaps.
Websites should also ensure flexibility by not using hard-coded encryption schemes so that they can update them as standards evolve in the future.
By planning and implementing these solutions in advance, organizations will protect themselves against future quantum attacks on their sensitive information while maintaining compatibility with their existing clients and systems.
