There is an increased amount of traffic on the network and for compliance reasons, management needs visibility into the encrypted traffic.
What is a result of enabling TLS/SSL decryption to allow this visibility?

Enabling TLS/SSL decryption allows visibility into encrypted traffic, which means that the data is decrypted so that security devices can inspect it. This is usually done by installing a trusted root certificate on the security device, which allows it to act as a proxy for SSL/TLS traffic.
The result of enabling TLS/SSL decryption is that management will have visibility into the encrypted traffic, which can help them monitor and enforce compliance policies. For example, they may be able to detect and prevent the transfer of sensitive data, such as credit card numbers or personal information.
However, there are some potential drawbacks to enabling TLS/SSL decryption.
One potential issue is that it may prompt the need for a corporate managed certificate. This is because the security device will need to present a valid SSL/TLS certificate to the end user, and if the certificate is not trusted by the user's browser, the user may receive warnings or errors. By using a corporate-managed certificate, the organization can ensure that the certificate is trusted by all users on the network.
Another potential issue is that enabling TLS/SSL decryption may fail if certificate pinning is enforced. Certificate pinning is a security mechanism that prevents man-in-the-middle attacks by ensuring that the client only accepts a specific certificate or set of certificates for a particular domain. If certificate pinning is enforced, the security device will not be able to act as a proxy for SSL/TLS traffic, and decryption will fail.
Enabling TLS/SSL decryption may also have a performance impact on the network. This is because the security device will need to decrypt and re-encrypt the traffic, which can consume additional processing power and bandwidth. However, modern security devices are designed to minimize this impact as much as possible.
Finally, it's important to note that enabling TLS/SSL decryption may be subject to privacy regulations, such as GDPR or CCPA. These regulations may require organizations to obtain user consent or provide other safeguards to protect user privacy when monitoring encrypted traffic. Organizations should consult with legal counsel to ensure that they are in compliance with all applicable regulations.
