ESET SSL scanning is a feature that allows or denies network communications based on a system of certificates that legitimate web services use to identify themselves. Sometimes, ESET SSL scanning might deny a legitimate web service or network device because its certificate changes frequently or does not use an SSL certificate. You can create exceptions to SSL scanning in ESET Windows home products to allow communications with these services or devices.
