With the shift to cloud computing IT environments have become highly distributed. Data and applications are accessible from anywhere in world, and are no longer secured by a traditional corporate network perimeter. However the workforce has become more distributed – employees need fast and secure connections to cloud services as well as corporate IT resources. This is why secure web gateways are now essential to cybersecurity as part of a layered security strategy.
As an overview an overview, a secure Web Gateway (SWG) is a method that blocks unwanted secure WiFi malware and software from live Internet browsers and enforces enterprise policies. This solution is similar to firewalls and CASBs, however it operates at the application level. It examines every request more thoroughly than traditional firewalls and assesses all files for malware and other threats that are evasive to detection.
A good SWG solution offers a combination of firewall inspection, URL and DNS filtering as well as antimalware, sandboxing Two-Factor Authentication (2FA), Web Application Firewalls (WAF) and more. It should also incorporate encryption. Encryption encodes data so cybercriminals are unable to read it, making sure that sensitive information doesn’t fall into the wrong hands.
A quality SWG will include a variety of features that are adapted to the specific requirements of your company. If you work in an industry that is highly restricted, your solution must include native data leak prevention as well as reporting compliance. If you have a significant remote workforce the solution should allow you to manage access to mobile devices that aren’t managed and enforce least privilege across your extended supply chains.
