(also secure web gateway)
Web security gateway definition
A web security gateway is a solution that provides strong cybersecurity measures to protect organizations’ networks and users from various online dangers. It is a barrier between the internal network and the internet, controlling and filtering web traffic.
By examining incoming and outgoing data packets, the web security gateway detects and stops harmful content, unauthorized access attempts, and potential security risks.
This gateway incorporates multiple security technologies to ensure comprehensive defense. For instance, it utilizes advanced techniques for web filtering, limiting access to malicious or inappropriate websites and preventing users from unintentionally downloading malware or falling prey to phishing attacks.
Additionally, it enforces secure browsing policies, like blocking specific categories of websites or implementing encryption protocols, to reduce the risk of data leakage or unauthorized data transmission.
