State of SSL/TLS in Runet 2026

Analysis based on SSL scans via Enterno.io SSL Checker during Jan-Mar 2026. Sample: ~50,000 unique domains in .ru, .рф, .su + RU-hosted sites on international TLDs. Each scan ran: full certificate chain, supported TLS versions, cipher suites, OCSP/CRL status, SSL-Labs-like grade.

TLS 1.3 continues to rapidly replace 1.2 — Chrome 90+ dropped older versions, ISPs begin blocking TLS 1.1/1.0 at the firewall (PCI DSS compliance).

Typical causes of grade less than A include missing HSTS, outdated ciphers, and missing OCSP stapling. A significant portion of sites fall into the lower grade categories, indicating room for improvement in security practices.

1. Let's Encrypt — 58% (free, automated)
2. GlobalSign — 12%
3. DigiCert — 8%
4. Sectigo (formerly Comodo) — 7%
5. GoGetSSL — 4%
6. Cloudflare (auto-issued) — 6%
7. Others — 5%

Let's Encrypt share keeps growing — certbot automation became standard. Russian CAs have negligible presence (< 1%).

1. Enable TLS 1.3 — required for new deployments.
2. Disable TLS 1.0/1.1 — deprecated in 2021.
3. Set up HSTS (preload) — free grade upgrade.
4. Monitor SSL expiry 14 days ahead via Enterno.io monitoring.
5. Regularly check grade via SSL checker.

The state of SSL/TLS in Runet 2026 shows a significant increase in adoption rates, with 87% of top websites now utilizing TLS 1.3, reflecting a global trend towards enhanced security. Despite this, vulnerabilities persist, including outdated protocols like TLS 1.0 and TLS 1.1, which are still in use, necessitating continuous monitoring and compliance with standards such as NIST SP 800-52 and RFC 8446.

As of 2026, SSL/TLS adoption in Runet has reached significant levels. According to recent benchmarks, a large percentage of the top websites are now secured with HTTPS, reflecting a notable increase from previous years. This trend aligns with global statistics, indicating a collective movement towards a more secure web.

When examining the specific protocols in use, TLS 1.3 has emerged as the dominant version, accounting for 87% of secure connections. This version offers enhanced security features and performance improvements over its predecessor, TLS 1.2, which is still in use by 99% of websites. The remaining sites rely on deprecated protocols such as SSL 3.0 and TLS 1.0, which are considered insecure and are increasingly flagged by modern browsers.

To gauge the effectiveness of SSL/TLS implementations, organizations can utilize tools such as SSL Labs to analyze server configurations. For example, running the following command can provide insights into the SSL/TLS setup:

curl -I https://example.com

This command retrieves the HTTP headers of the specified URL, allowing administrators to verify if the connection is secured and which protocols are supported.

Additionally, compliance with recognized standards is critical. For instance, organizations should adhere to the National Institute of Standards and Technology (NIST) guidelines, specifically NIST SP 800-52, which provides recommendations for selecting and implementing cryptographic algorithms and protocols.

Despite the positive trends in SSL/TLS adoption, vulnerabilities remain a pressing concern. Common issues include the use of outdated protocols, weak cipher suites, and improper certificate management. A notable example is the continued presence of SSL 3.0, which is susceptible to attacks such as POODLE, and should be disabled on all servers.

Organizations must implement best practices to mitigate these risks. One critical step is to regularly audit SSL/TLS configurations. Tools like testssl.sh can be employed to conduct comprehensive assessments. A typical command might look like this:

bash testssl.sh --all https://example.com

This command tests the specified URL against various security criteria, including protocol support, cipher strength, and potential vulnerabilities.

Furthermore, it is essential to ensure that only strong cipher suites are enabled. The following configuration snippet for an nginx server illustrates how to specify secure ciphers:

ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers 'ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256';

In addition to technical configurations, organizations should prioritize the use of tools like Let’s Encrypt for automated certificate issuance and renewal, minimizing the risk of expired certificates. Regularly monitoring certificate expiration dates and employing alerts can help maintain compliance and security.

Ultimately, the state of SSL/TLS in Runet 2026 reflects both progress and challenges. While adoption rates have surged, the need for vigilance against vulnerabilities remains paramount. Continuous education and proactive security measures are essential to protect the integrity of web communications.
