70% of the worldwide web-traffic is SSL-encrypted (https)


50% of all malware hides behind SSL-encryption


Easy certificate handling which automatically syncs in the hole “Secucloud SASE” Cloud Network around the world will assists you securing your global enterprise WAN and central Internet policy enforcement. Exclude sensitive traffic from getting decrypted. E.g. by excluding the content-category “Banking” or creating a custom whitelist of URLs which should never be decrypted, you will keep the company compliances.



To be able to perform a complete SSL-Inspection the data traffic must be handed over to an inspection instance in which the information is decrypted. After analysis of the traffic, the data is encrypted again and passed on to the intended destination. All additional requests to be encrypted must be signed again by a new certification body.
For SSL-Interception the SSL Man-in-the-middle (MITM) approach is used.

  1. As before, the browser calls the URL of the HTTPS server but this time the connection is terminated by the HTTPS proxy.
  2. The HTTPS proxy then establishes a connection itself to the target server.
  3. The HTTPS server answers by sending its certificate to the proxy.
  4. Just like the browser, the HTTPS proxy requires a list of trustworthy CAs so it can verify that it is really communicating with the requested HTTPS server. Using this list, the certificate sent in (3) is checked.
  5. If the certificate is valid, the first encrypted connection is established between the HTTPS proxy and the HTTPS server.
  6. The original connection initiated between the browser and the HTTPS proxy in (1) isn’t answered until all the above steps are complete. The HTTPS proxy now sends a self-created certificate which indicates that the owner is the HTTPS server and is not signed by an official CA. Instead, the HTTPS proxy has its own CA which signs the certificate it created.
  7. This CA is, of course, not in the browser’s CA list, so the HTTPS page is only loaded after a security warning has appeared and asked for the user’s express permission to display it. To avoid that happening, the company’s IT administrator would need to copy the HTTPS proxy’s CA into the CA lists of all its browsers. However, this is easy to do in Windows environments with Windows Group Policy Management.
  8. Once all this has been done, the second encrypted connection between the browser and the HTTPS proxy is established. At this point, the data is sent by the HTTPS server to the HTTPS proxy, and as it is unencrypted it can be scanned there to check for Malware and content-filtering. If no unwanted traffic is present, the data is sent to the browser via the second HTTPS connection. This method ensures that the data cannot be read – neither in the local network nor on the internet – but can be checked within the firewall and any viruses present can be blocked.

In this way, the “Secucloud SASE” service with an SSL proxy increase the security of company networks, because they close the last loophole.


Secucloud links superior machine learning technology with the multi source input network to continuously improve the Global Cloud Intelligence and to rapidly classify domains, URLs, IPs and files with great coverage, accuracy and speed.

Another technique to ensure continuous tracking and unique accuracy is to determine via proprietary AI algorithms how deeply a given site should be scanned. For example, site dynamics and typical user interactions with a given site are factors in these algorithms. Secuclouds’ contextual analysis determines in which case to deeply scan sites, using different methods:

  • AI analyzing the site dynamics and user behavior

  • Customer-oriented classification

  • Exact URL classification at any given time due to continuous tracking
