# Proofpoint Alternatives in 2026: Keep Proofpoint, Add Voice and Callback Source: https://keepnetlabs.com/blog/keepnet-proofpoint-alternative Published: 2026-08-27 Updated: 2026-09-29 Author: Ozan Ucar, Founder and CEO of Keepnet Category: Security Awareness Training > Looking at Proofpoint alternatives? You may not need to replace it. Keepnet adds live voice and callback simulation alongside ZenGuide and your gateway. **You do not have to replace Proofpoint to close the gap**. Most teams keep the email gateway and ZenGuide, and add Keepnet for the part Proofpoint does not simulate: a real phone call to the employee's own phone, and callback phishing where the employee dials the number and speaks to someone. Licenses can be co-termed to your existing contract, so this is an extension rather than a migration. **One scoping note first**. Proofpoint is a large product family, and Keepnet is not an alternative to most of it. Email security, data loss prevention, archiving and insider threat management sit outside what Keepnet does, and if you run them there is no reason to change. This comparison covers one module of that family: ZenGuide, the security awareness training and phishing simulation product. Teams looking at Proofpoint alternatives are usually not unhappy with the email side. Proofpoint's own 2026 ZenGuide solution brief says its simulations reflect QR code threats, AI exploits, telephone-oriented attack delivery and email bombing, and its simulation pages list email, SMS, smishing and USB campaigns. The gap is narrower than most comparison articles suggest, and it sits in one place: the phone call itself. ## What Does Proofpoint Do Well? Proofpoint starts from the gateway. Most buyers already run its email security, which gives ZenGuide something a standalone awareness tool cannot get on its own: live telemetry about who is actually being attacked. Users identified as Very Attacked People, repeat clickers, or people exposed to active credential threats can be enrolled into training automatically. ThreatFlip is the clearest example. A real phishing email that reached your organization is cloned, stripped of its harmful parts and turned into a safe simulation template in one click. Teachable Moments then explain the attacker technique at the moment someone interacts with a simulation, rather than in a course weeks later. On channels, Proofpoint documents email, SMS and smishing, and USB campaigns, with lures modeled on QR code threats, AI exploits, telephone-oriented attack delivery and email bombing. Anyone telling you Proofpoint is email only has not read the current product pages. ## Why Teams Look for a Proofpoint Alternative Three reasons come up most often. The phone call is a lure, not a channel. Telephone-oriented attack delivery is simulated as an email that carries a number. The failure that matters happens after the employee dials, and neither the email nor the follow-up training measures that conversation. In the 2026 Verizon Data Breach Investigations Report, phone-centric simulations show a median click near 2 percent against about 1.4 percent for email (p. 50), so the channel that is not being tested is the one people fail more often. The strongest features assume you also own the gateway. Proofpoint's own brief describes live telemetry, automatic enrollment of Very Attacked People and enriched reporting as benefits of integrating ZenGuide with its Collaboration Security platform. If your email security sits with Microsoft or another vendor, part of what you are paying for stays out of reach. Reporting stops at the inbox. When a suspicious message arrives as a text or a call, there is no reporting path in the email client, so those events never enter the queue and never appear in the numbers. ## How Keepnet Is Different Keepnet runs simulations on six channels from one platform: email, [voice](https://keepnetlabs.com/products/vishing), [SMS](https://keepnetlabs.com/products/smishing-simulator), [QR code](https://keepnetlabs.com/products/quishing-simulator), [callback](https://keepnetlabs.com/products/callback-phishing) and deepfake. Each channel has its own campaign manager and its own susceptibility reporting, so a weak channel stays visible instead of being averaged away. Voice simulations place an actual call to the employee's own phone, from one of your own local numbers, in their own language, and use a two way AI conversation rather than a recorded message. Callback phishing is simulated as its own channel: the employee dials the number and reaches an agent, which is the point where a telephone-oriented attack actually succeeds or fails. Your Proofpoint gateway can be tested as well. [Email Threat Simulator](https://keepnetlabs.com/products/email-threat-simulator) sends benign versions of current attacks through your own configuration and reports what got through. That is a configuration check on the gateway you already pay for, not a replacement for it. Every product can be bought on its own. The [security awareness training library](https://keepnetlabs.com/products/security-awareness-training) is optional, so a team that only needs the missing channels can take only those. The platform is SCORM compatible, so training content you already built or licensed can stay where it is. The AI layer is agent based rather than a single assistant. Specialized agents plan, create, deliver, measure and improve continuously, and an admin chooses between approval gated and autonomous execution. Generation is grounded in documents you upload, the platform keeps an organizational memory, personal data is stripped before anything reaches the model, and the AI provider is configured for no retention and no training. Localization goes past translation. Templates are adapted per region, including subject lines, body copy, currency, date format and tone, and the training library ships in 61 languages. Employees can report a suspicious SMS or call from the phone itself through the Keepnet SMS and Call Reporter, and those reports land in [Incident Responder](https://keepnetlabs.com/products/incident-responder) next to reported email. ![Diagram showing six simulation channels, each with its own susceptibility score: email, voice, SMS, QR code, callback and deepfake, all feeding into one reporting workflow.](https://timely-benefit-e63d540317.media.strapiapp.com/keepnet_per_channel_susceptibility_96cdf9fcb2.png) *Susceptibility measured per channel, not as a single organization wide average.* ## Keepnet vs Proofpoint: What to Compare **Keepnet compared with Proofpoint** | Dimension | Keepnet | What to check on any alternative | | -------------------------- | -------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------- | | Simulation channels | Email, voice, SMS, QR, callback and deepfake, each with its own susceptibility report | Proofpoint documents email, SMS and smishing, and USB, with QR code and telephone-oriented lures.

Yes, and for Proofpoint accounts this is usually the sensible order. The gateway stays where it is, ZenGuide keeps running for email, and Keepnet is added for voice, callback, SMS and QR. Additional licenses can be co-termed to your existing contract, so renewal dates line up and nothing has to be torn out mid-term. Reporting buttons can coexist, and phone reports arrive in Incident Responder rather than competing with your email queue. ## Which Proofpoint Alternative Fits Your Reason? If the reason is the phone, look for a platform that places a real call and reports on what happened during it, not one that sends an email carrying a phone number. If the reason is gateway independence, check which capabilities are only available when you also buy that vendor email security, and price the program without them. If the reason is content or engagement, be honest that Proofpoint is strong here. ThreatFlip and Teachable Moments are good pieces of product, and a channel gap is not a reason to give them up. If the reason is measurement, ask what the platform reports beyond completion. 84 percent of security leaders track training completion as a top metric (Gartner, 2025 Secure Behavior Strategies Survey, n=65), while the human element appeared in 62 percent of breaches in the 2026 Verizon DBIR. Completion is not the same as behavior. ## See It on Your Own Environment The fastest way to compare is a short pilot on the channel you cannot currently test.

Proofpoint is an email security vendor whose platform also includes ZenGuide, its security awareness training product. Most buyers arrive at ZenGuide because they already run Proofpoint email security. ### Does Proofpoint do more than email simulations? Yes. Proofpoint documents email, SMS and smishing, and USB campaigns, and its 2026 ZenGuide brief says simulations reflect QR code threats, AI exploits, telephone-oriented attack delivery and email bombing. The gap is not email versus everything else, it is the live phone call. ### Why do teams look for Proofpoint alternatives? Usually for three reasons: the phone attack is simulated as an email lure rather than an actual call, several of the strongest ZenGuide features assume you also own Proofpoint email security, and there is no reporting path for a message that arrives as a text or a call. ### How is Keepnet different from Proofpoint? Keepnet places a real phone call to the employee own phone, from one of your own local numbers, in their own language, using a two way AI conversation. Callback phishing is its own channel, where the employee dials and speaks to an agent. Each of the six channels reports susceptibility separately, and every product can be bought on its own. ### Can I run Keepnet alongside Proofpoint? Yes. The gateway and ZenGuide stay in place and Keepnet is added for the channels they do not simulate. Additional licenses can be co-termed to your existing contract. ### Can Keepnet test my Proofpoint configuration? Yes. Email Threat Simulator sends benign versions of current attacks through your own email security and reports what got through, which is a configuration check rather than a replacement. ### Can I keep my existing training content? Yes. The platform is SCORM compatible, so content you already built or licensed can stay in place. ### How do employees report a suspicious SMS or call? Through the Keepnet SMS and Call Reporter, currently available on the App Store for iPhone. An Android version is planned. Reports land in Incident Responder next to reported email, and the data can be exported through the REST API or pushed to a SIEM. ### How many languages does Keepnet support? The training library ships with content in 61 languages, and localization goes past translation: templates are adapted per region, including subject lines, currency, date format and tone. ### Which is better for a large enterprise already on Proofpoint? For email, staying on Proofpoint is usually the cheaper answer. The question worth asking is what your program currently reports about voice and callback, because that is where the gap sits and where phone-centric simulations fail more often than email in the 2026 Verizon DBIR.
