SASE , or secure access service edge , located in the cloud , offers a holistic solution to provide a secure environment in an era of zero trust

Tamlin Magee

Cybersecurity management at a distance can be a headache , even before the pandemic hit and remote working became the norm for many . That businesses had already moved enthusiastically towards cloudbased ways of working made old forms of network defence , the so-called castle-and-moat approach , less viable . A certain level of control had to be ceded .

Over the years , approaches such as CASB , or cloud access security brokers , firewall-as-a-service and identity and access management went some way towards assisting companies to build better defences .

But without a joined-up , holistic deployment strategy , organisations still lacked the visibility necessary to manage security in the digital-first cloud world .

These technologies , and more , are now being bundled together under the umbrella of SASE , secure access service edge , pronounced “ sassy ”, with a service wrap that ’ s easy to sell and pay for , says TechMarketView principal analyst Martin Courtney . Because the framework is cloud native , SASE-led programmes lend themselves well to zero-trust networks , which guarantee no single person is given inappropriate credentials by default .

The idea is to enable secure access on a case-bycase basis , giving users permissions they need to accomplish a specific task , rather than letting them into the entire network . SASE promises to bring reduced cost , less complexity and fewer integration challenges across an organisation , with better visibility . p
