When the world witnessed some of the largest cyberattacks in the last two or three years – including SolarWinds, Colonial Pipeline and more – it became loud and clear that the security landscape is evolving exponentially.
Essentially, SASE tackles the latency and security problems together by converging network and security. It offers not just speed (this is a win-win situation for businesses looking to marry network and security happily). Additionally, SASE reduces complexity and introduces more efficiency, visibility, and control over security architectures.
All these advantages bundled together make SASE a lucrative option for businesses. It is gaining ground faster than expected. SASE adoption by enterprises in 2018 was about one percent – but Gartner predicts that about 40 percent of them will develop strategies with SASE factored in by 2024.
As a matter of fact, the pandemic has been an accelerating force for the growth of SASE. With many of the employees working from home, the number of devices connected to the corporate networks has risen manifold. Before the pandemic, IT departments would typically see a “distributed workforce” as a synonym for branch premises spread across the globe. But with the pandemic setting in, each of the employees working from home is a branch in themselves.
When the reality of the pandemic hit, businesses saw tens of thousands of employees suddenly working from home. And they wanted access to apps like Zoom and MS Teams. The most common problem was network congestion. Solutions centered around SASE solved this problem effortlessly, but those relying on a traditional VPN setup had to go through considerable turmoil.
This “hyper-distributed” workforce is not going to fade away soon. On the contrary: it will become a normal way of working with companies now adopting hybrid work, and some even offering a permanent remote work option to their employees.
In the wake of a growing number of attacks, cybersecurity is an overriding concern for organizations. According to a report by cybersecurity ventures, global cybercrime costs in 2015 stood at USD 3 trillion, whereas by 2025, the figure is set to reach USD 10.5 trillion.
It is expected that such trends will drive enterprises even more strongly to adopt SASE. The Gartner report on SASE convergence 2021 stressed the fact that security architecture must undergo changes so that security could be delivered through the cloud.
The shift from traditional networking concepts to SASE is the first step in implementing real zero-trust-based models. Perimeter-based network security no longer serves the purpose of the distributed workforce and cloud workloads.
