Why do I need SSL certificates for my websites?
Websites with SSL certificates are trusted by browsers, search engines and users.
To prevent browsers from marking your websites as unsafe
If a website does not have an SSL certificate installed or it has expired, visitors will see a message in their browser that the website is not secure. Such messages make you mistrust the resource.
To use a secure encrypted HTTPS connection
HTTPS is a protocol for transferring data between a website and the computers of its visitors. Data that is transmitted over HTTPS is encrypted, so attackers cannot take advantage of it. An SSL certificate from Let's Encrypt confirms that the website uses an HTTPS connection of proper quality.
To rank better in search results
Google recommends installing SSL certificates for any website, even if it is a small blog or a business card website that does not collect user data. Search services will pessimize websites without SSL certificate in their search results.

Limitations of free Let's Encrypt SSL certificates
We do not recommend using Let's Encrypt DV certificates for websites, which collect personal data or accept payments. A DV certificate verifies only the right to the domain. It does not guarantee that the website belongs to an officially valid organization. For corporate portals, online stores and any commercial resources we recommend buying certificates of EV or OV levels. They are also available from us.

Can I protect my domain and subdomains at once with a certificate from Let's Encrypt?
Yes. One certificate can protect a group of subdomains or all subdomains (wildcard certificates).
Why are Let's Encrypt certificates only valid for 90 days?
According to Let's Encrypt, this validity period has two advantages:
- This is how the certificate authority limits the damage from compromised keys and erroneously issued certificates. The less time the certificate is used in this way, the less damage it will do.
- A 90-day limited validity period of SSL certificate encourages automatic reissuing (this feature is supported by ISPmanager) and accelerates mass migration to the secure HTTPS protocol.
Let's Encrypt recommends that you renew your certificates every 60 days if necessary for any reason.
Does Let's Encrypt generate a Private Key for my certificate on its servers?
No. The private key is generated only on your servers, not on the Let's Encrypt Certification Authority server.
If you are a hosting provider
Many users host non-commercial websites. Let's Encrypt SSL certificates are a great solution for such cases. Clients get free domain protection, and this increases their loyalty.
