Vulnerabilities of a secure SSL connection

Explanation of each sequence:

TLS is a data transfer protocol. Can be equal to TLS1, TLS1.1, SSLv3, etc.
ECDHE is a temporary (ephemeral) key.
ECDSA is an authentication algorithm.
AES 128 GCM is a symmetric encryption algorithm.
SHA256 is a data hashing algorithm.

All these components should be safe both individually and in combination.

We check:

Vulnerability of the cipher suites available for use by your server. We check for the presence of obviously vulnerable cipher suites: NULL, aNULL, EXPORT, LOW,3DES_IDEA, OBSOLETE, STRONG_NOFS.
Using the modern SSL connection protocol.
Support for advanced encryption standards.
19 types of popular attacks using SSL such as: heartbleed, CCS, ticketbleed, ROBOT, secure renego, secure client renego, CRIME TLS, POODLE SSL, fallback SCSV, SWEET32, FREAK, DROWN, DROWN hint, LOGJAM, LOGJAM common primes, BEAST, LUCKY13, winshock. The possibility of these attacks is a serious security problem.

Due to the presence of a critical vulnerability, you will most likely get into all the lock sheets, as your site is easily hacked. Browser and search engine manufacturers maintain a registry of unsafe sites. The presence of vulnerability is also a reason to get on such a list. Most likely, you will be excluded from being shown in search results, and the browser will show a security warning when going to your site.
