Outdated certificates are a security threat

The faster digitization moves into all areas of life, the greater the importance of online services for the economy. At the same time, the number of cyberattacks continues to grow – at breakneck speed. Companies are increasingly facing cyber attacks, data thefts and industrial espionage. The result: financial losses created by reduced sales or damage to their image that could cost billions. When it comes to IT security, the time to fortify lines of defense has arrived.

SSL creates confidence

SSL certificates (secure sockets layer or TLS certificates (transport layer security)) are basic components of such defense lines. They facilitate secure data transmission and create a new foundation of trust. The digital ID lowers the risk of being lured to the wrong website by hackers, a maneuver that can be used to steal address or even account data. In online banking, encryption via HTTPS protocol with an SSL certificate is now widely used. Secure and reliable web connections are also essential in a business setting, including in online shopping from digitized catalogues, the orchestration of suppliers via online portals or the large intranets of major companies.

Google to clean house

But that is not all: Any company that has not kept pace with SSL developments runs the risk of seeing its online processes soon classified as insecure. In 2018, Google will withdraw authorization for a large number of older SSL certificates for security reasons. This process will affect all people who use Chrome as a browser – one-third of all Internet users, mind you. The transition will be done in stages starting with Chrome 66 and be concluded in fall 2018 with Chrome 70. Websites with outdated SSL certificates will no longer appear in search results, or will be displayed with a security warning.
