Transport Layer Security (TLS) certificates, also known as Secure Sockets Layer (SSL), are essential to securing internet browser connections and transactions through data encryption. TLS (Transport Layer Security) is just an updated, more secure, version of SSL.

An SSL certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. SSL stands for Secure Sockets Layer, a security protocol that creates an encrypted link between a web server and a web browser.

HTTPS (Hyper Text Transfer Protocol Secure) appears in the URL when a website is secured by an SSL certificate. The details of the certificate, including the issuing authority and the corporate name of the website owner, can be viewed by clicking on the lock symbol on the browser bar.

All data on the Internet flows through many nodes, through many devices, when using WiFi they reach the wide vicinity of the transmitter - this data and not only that, it is necessary to protect it securely against eavesdropping and misuse. For this, SSL certificates are used, which help to encrypt internet communication, so that no intruder can, for example, get access to data from a web form where personal data, credit card numbers or passwords are filled. Secure communication also ensures that no one can find out what content you are viewing on the Internet, no one can fraudulently insert malicious code or advertising into the page. In addition to the security of data transmission, the HTTPS certificate enables the use of modern technologies, such as the HTTP/2 protocol, which increases the loading speed of web pages and, last but not least, increases the SEO ranking of pages in the Google search engine.
The time when SSL certificates were expensive is long gone, you can get an SSL certificate for FREE or, for example, PositiveSSL certificates for a few hundred crowns. Every company or website operator should install an SSL certificate on their website as soon as possible, otherwise they will be considered untrustworthy and will lose visitors.

  • HTTPS communication
    The SSL certificate ensures the establishment of secure, encrypted communication between the user's browser and the server, in order to minimize the possibility of eavesdropping and at the same time the content cannot be changed or forged or dangerous code can be inserted into the page.
  • Verified communication
    The SSL certificate confirms the authenticity of the server and its operator with whom the user communicates, and it is also possible to identify the client vis-a-vis the server. Company SSL certificates and EV certificates contain information about the company operating the website.
  • Higher SEO ranking
    The success of websites is very often linked to high-quality SEO optimization and placement in leading positions in search engines. Google strongly supports secure HTTPS communication and gives sites with an SSL certificate a higher ranking.
  • A faster website with HTTP/2
    New technologies cannot do without an SSL certificate. The new, significantly faster HTTP/2 protocol only works with HTTPS communication. Fast page loading is important for customers and for higher search engine rankings.
  • Notation "Unsecured"
    Websites without an SSL certificate are negatively labeled "NOT SECURE" in the Google Chrome browser. No website owner wants to have such a label and appear untrustworthy.
  • SSL certificate is required
    The creators of Chrome, Firefox, Safari and others are aware of the importance of secure communication using an HTTPS certificate. They will increasingly and prominently point out insecure websites.

  • Certification Authority is a trusted organization that provides authentication of a public key. Before issuing an SSL certificate, the authority must perform validation that follows the CA conditions and CA/Browser forum.
  • CA/Browser forum is a voluntary association of certification authorities, creators of browsers and operating systems that defines rules in the field of Internet security regarding https communication and issuing certificates.
  • CAA record (Certification Authority Authorization) record is a record in a domain's DNS zone that tells which certification authority is allowed to issue an SSL certificate to the domain. CAA records are another piece to increase security on the Internet.
  • Certificate Revocation List (CRL) contains a list of certificates that have been revoked during their validity. Each CA adds to its list issued and no longer trusted certificates where revocation has been requested, for example due to a private key compromise. Revocation List thus allows you to verify the validity of the certificate.
