How to Choose the Right SASE Vendor in the AI Era

Understanding AI and SASE Trends

Whichever car you've boarded on the AI train, it's going places, and not all of them good. Earlier this year, we predicted that most threat actors would start using AI to enhance and automate attacks in 2025. So far, we've seen plenty of evidence of that, like threat actors using GenAI to create lookalike government websites, or capitalizing on AI hype to lure users to a fraudulent DeepSeek page.

In that same post, we also predicted that AI and automation would redefine threat detection and response. Indeed, most cybersecurity vendors now incorporate AI in their offerings in one way or another. But let's set that part of the conversation aside for a moment.

The other train selling lots of tickets lately is, of course, the secure access service edge (SASE). Since 2019, this framework has gained momentum as a way for organizations to enhance security, simplify management, improve network performance, and reduce costs all at once. SASE unifies a core set of networking and security solutions, including:

• SD-WAN to connect global locations and route network traffic
• Secure web gateway (SWG) to filter and secure web traffic
• Zero trust network access (ZTNA) to secure access to private apps
• Cloud access security broker (CASB) to monitor and control SaaS usage
• Firewall as a service (FWaaS) to inspect other traffic and stop threats

With remote and hybrid work models thriving, it's easy to see the appeal of a simple, cost-effective way to bring all that together. That's probably why Gartner predicts the SASE market will grow 26% each year through at least 2028.

As SASE and AI mature, leading SASE vendors are finding innovative ways to empower one with the other. AI-powered analysis can uncover new and evolving threats. AI-powered threat intelligence can drive smarter policy. AI-powered behavioral analysis can rapidly spot insider threats.

That brings us to the key question: in today's crowded SASE market, how do you find the right vendor for your organization?

Selecting the Right SASE Vendor

Get a unified platform with simple management
To simplify your operations, you need intuitive, single-pane management for policy enforcement and analytics. Features like data loss prevention (DLP), user monitoring, and malware protection should all work together without giving your admins “swivel-chair syndrome.” And to keep your users happy, your SASE solution should make it easy to identify and troubleshoot user experience issues.

Insist on a true zero trust solution
Any vendor can call their solution “SASE,” but they can't all follow through on SASE's biggest promises. Steer clear of offerings that simply package firewalls in the cloud and call it SASE, opening you up to lateral threat movement and other risks. Look for a platform built on a cloud native zero trust architecture, so only verified users can access authorized apps, without ever touching your network.

Opt for simple, effective segmentation
You need segmentation to protect your users, apps, and devices, but legacy architectures aren't suited to cloud-first environments. They tend to have static network designs, rigid controls, and a lot to manually configure, making segmentation complex and time-consuming. SASE built on a zero trust architecture simplifies segmentation with automated enforcement, avoiding the need for constant manual tuning.

Demand comprehensive security and data protection
The best threat protection and data security won't mean much if they leave blind spots. Choose a SASE platform that enforces advanced protection in real time, with complete visibility into where your data resides or moves. Adaptive access controls, risk-based policies, ongoing verification, and AI-powered threat detection are also critical to stop leaks and attacks across all your channels.

Don't compromise on scalability and reach
Secure access services are key, but don't forget the “edge.” Select a SASE vendor that offers globally distributed points of presence (PoPs) to deliver services as close as possible to your users, no matter where they are. Also, make sure your vendor offers secure connectivity functions that can handle distributed, high-demand workloads to give you a consistently high quality of service.

Choose a vendor that leads in AI innovation
As the saying goes, you have to fight AI with AI. Go with a SASE vendor that seamlessly integrates AI in their platform for smarter security, faster responses, and better performance. Capabilities like real-time risk scoring, AI-driven threat detection, and automated policy adjustments are essential to respond to AI-enhanced threats. The most effective solutions can also use AI to enrich incident context, adapt to evolving risks, and simplify management.
