Adaptive Security Alternatives in 2026: Where the Channel Argument Ends

Adaptive Security is one of the few vendors in this category that genuinely runs simulations beyond email. If you are comparing it with Keepnet, the honest starting point is that the channel argument does not settle this one.

One scoping note first. Adaptive Security also sells email security and AI governance. Keepnet does not replace an email gateway or filter inbound mail, so those parts sit outside this comparison. What follows covers the simulation and awareness side, where the two products actually overlap.

What Does Adaptive Security Do Well?

Their product pages document email, voice and SMS phishing simulations plus deepfake attacks, run across the organization. That is a wider set than most competitors in this category can claim, and it should be taken at face value.

The content side is substantial as well: a library described as more than a thousand resources covering AI threats, phishing, voice cloning and compliance, with custom modules that can be generated from your own policies.

They are also new, well funded and moving quickly, which shows in how often they turn up in comparison searches. Buyers are searching Adaptive Security against one competitor after another, which is usually a sign that a vendor has landed in real shortlists.

Where Keepnet Is Different

Four differences hold up when you look at what each product documents.

More channels, and each one measured on its own. Keepnet simulates email, voice, SMS, QR, callback and MFA fatigue as well as deepfake. QR and callback are separate channels here with their own susceptibility reports. Adaptive Security product pages document email, voice, SMS and deepfake, and do not describe QR or callback simulation as products.

What happens after the employee spots it. Simulation tells you who is likely to fall for an attack. It does not tell you what happens when a real one arrives. Keepnet puts a report button in the inbox and on the phone, and routes what comes back into Incident Responder for automated analysis. Reporting and response are a documented product line rather than a feature note.

Mobile reporting. When the attack is a text message or a call, most programs have no reporting path at all. Keepnet Reporter gives employees one on the device where the attack lands, and those reports join the same queue as email reports.

It runs next to what you already own. Keepnet does not filter your mail, so it sits alongside Microsoft, Proofpoint, Mimecast or whatever you run today. Employees keep the native Microsoft report button and reports go to both Defender and Keepnet. Training is SCORM compatible and runs inside the LMS you already use.

The phone channel is worth measuring separately whichever vendor you pick. In the 2026 Verizon Data Breach Investigations Report, the median click rate is about 1.4 percent on email simulations and about 2 percent on phone-centric ones (Verizon, 2026 Data Breach Investigations Report, 2026, p. 50).

Voice simulations place an actual call to the employee own phone, from one of your local numbers, with a two way AI conversation rather than a recording. See vishing simulation, smishing simulation, quishing simulation and callback phishing simulation.

Keepnet vs Adaptive Security: What to Compare

Keepnet compared with Adaptive Security

Can You Run Both?

You can, and some teams do while they decide. Keepnet does not touch mail flow, so it can be added next to anything without a migration. Running one channel through each platform for a cycle is the cleanest way to compare the reporting side, which is where the two products differ most.

Which Alternative Fits Your Reason?

If the reason is coverage, check QR, callback and MFA fatigue specifically, not just the headline list of channels.

If the reason is what happens after the report, ask to see the triage queue, not the simulation dashboard.

If the reason is mobile, ask where an employee reports a text message or a call, and where that report ends up.

If the reason is content, both sides have large libraries. The better question is whether the content adapts by role, language and region, and whether it runs in the LMS you already own.

See It on Your Own Environment

A short pilot settles this faster than a feature table. One voice campaign, one SMS campaign and one reported message end to end will show you how each platform behaves. Book a demo and we will run it on your own users.
