Zero Trust Software Resources

I’ve been looking into zero-trust software lately, especially free tools that could work for small or growing teams. I’m seeing a lot of conversations about whether free versions actually provide enough protection or if they’re more suited just for early testing.

For those who’ve used free zero-trust platforms, how did they hold up once more people or apps were added? Did you stick with the free plan or eventually have to move to a paid version?

I’m looking at zero trust networking software and came across these top-rated tools on G2. I’d be interested in your experience if you've used any of them. Here are the ones I’ve been looking at:

Palo Alto Networks IoT/OT Security

Built to secure connected devices across both IT and operational environments. From what I’ve read, it’s strong on visibility and control in more complex setups.

Okta

Known for identity-based access, Okta helps teams control and verify who can access what, especially across remote apps and devices.

Zscaler Private Access

Offers secure access to internal applications without using traditional VPNs. It's often recommended for organizations moving toward full zero trust.

Forcepoint ONE

Combines web, cloud, and private app access in one platform. From what I can tell, it’s built for companies that want one control point for different access needs.

Absolute Secure Access

Focuses on securing endpoints and maintaining secure connections even under poor network conditions. Looks helpful for distributed or field-based teams.

A quick takeaway would be helpful if you’ve used any of these.
