Trend Micro SSL Certificates

Always-on SSL

Some organizations switch users between secure and non-secure windows during sessions to save money on SSL certificates, which can leave sensitive information exposed. Always-on SSL protects a user’s entire session from start to finish, ensuring a safer experience. But implementing always-on SSL has been expensive and hard to manage—until now. Trend Micro SSL provides unlimited SSL certificates, including Extended Validation (EV) certificates, and a management console so you can protect every web page cost-effectively. Trend Micro is a globally trusted Certificate Authority (CA) so you can be sure your websites—and your customers are protected.

Types of SSL Certificates

Organization Validation (OV) Certificate:
Increase visitor trust and protect communications
An OV certificate gives your website credibility by showing a browser padlock and HTTPS to site visitors. Vetted company information is displayed in the certificate details, verifying your corporate identity, and assuring potential customers that you take security very seriously. Trend Micro OV certificates support the strongest level encryption and authentication to protect all communications between servers and users.

Extended Validation (EV) Certificate: 
Activate the green bar for the highest trust and conversions
When EV certificates are used, the browser address bar turns green—assuring site visitors that they are on a trusted site and their personal data is protected. This has been shown to significantly increase sales and conversion rates. EV certificates require rigorous vetting procedures involving meticulous documentation checks to confirm both website and organization authenticity. Unfortunately, the high cost of EV certificates combined with the onerous vetting process means they aren’t broadly used. With Trend Micro SSL, we provide unlimited EV certificates at no extra cost. And, with our one-time vetting process, you can issue EV certificates in minutes vs. the days or weeks required with other CAs.

Extended Validation Certificate

Unified Communications Certificate (UC) or Subject Alternative Name (SAN) Certificate:
Get cost-effective SSL for Microsoft Exchange servers
With a UC or SAN certificate, you can use one SSL certificate to secure host names on different base domains such as: and Hosting multiple SSL-enabled sites on a single server typically requires a separate IP address for each site, but a certificate with SAN support can solve this problem. This is also perfect solution for Microsoft Exchange servers.

Wildcard SSL:
Secure all servers and subdomains on a given domain
A Wildcard SSL certificate enables you to secure a website’s domain and an unlimited number of its subdomains. For example, a single Wildcard certificate for *, covers both and
