The best deepfake phishing simulation tools in 2026: Cyber Aware is the best overall pick for SMBs and MSPs who want AI voice-scam awareness running inside a managed monthly programme, Hoxhunt leads for live deepfake video-meeting attacks, and Breacher.ai is the red-team-grade option for organisations that need a full-scale deepfake exercise rather than a subscription.
TL;DR
- Cyber Aware is the best deepfake phishing simulation tool overall in 2026 for SMBs and MSPs running managed awareness programmes.
- Hoxhunt leads for live deepfake video meetings: a phishing email routes staff into a fake Teams or Zoom call with a cloned executive avatar.
- KnowBe4 added simulated vishing calls in 2026, but its deepfake coverage is content-led rather than live-call simulation.
- Deloitte projects generative-AI-enabled fraud losses in the United States to reach $40 billion by 2027, up from $12.3 billion in 2023.
- Arup lost $25 million in 2024 to a video call in which every participant except one was a deepfake.
Why deepfake phishing needs its own simulation layer in 2026
In 2024, a finance employee at engineering firm Arup in Hong Kong transferred $25 million (HK$200 million) after a video call in which every other participant — including the "chief financial officer" — was a deepfake (BBC News). The email that started it was suspicious enough that the employee suspected phishing. The video call was what closed the deal.
Deloitte's Center for Financial Services projects that generative-AI-enabled fraud losses in the United States will reach $40 billion by 2027, up from $12.3 billion in 2023 — a 32% compound annual growth rate (Deloitte Insights). Hoxhunt's Phishing Trends Report 2026 found that 43% of business email compromise attacks now include a callback lure — the move from the inbox into a phone call or video meeting, exactly where deepfakes live.
Most phishing simulation tools never leave the inbox. A deepfake phishing simulation tool is the class of tool that follows the attack into the voice channel and the video call, so staff practise the verification step that stops a real one — the always-on layer behind Cyber Aware's phishing platform.
What makes the best deepfake phishing simulation tool
Judge every option on six criteria:
- Voice realism. AI-generated voice that adapts during the scenario, not a pre-recorded clip looped over the line.
- Channel coverage. Email into Teams or Zoom meetings, phone calls and SMS — attackers chain channels, so simulations should too.
- Safe execution. No credential harvesting, no real payments — every scenario runs in a controlled environment.
- Auto-remediation. A fail immediately enrolls the person into a focused lesson, not a manual follow-up email.
- Reporting an executive reads. Per-person risk scores and trend lines, not attendance lists.
- Cadence that runs itself. A programme that stops when the admin stops feeding it has already stopped.

1. Cyber Aware: best deepfake phishing simulation tool for SMBs and MSPs
Cyber Aware runs 100+ phishing templates, from invoice fraud to AI voice scams, with AI-generated variants refreshed weekly. Anyone who clicks is auto-enrolled into a failed-phishing course the same day, and every learner carries a monthly Human Risk Score built from overdue courses, quiz failures and phishing clicks. The vendor reports an average 80% reduction in clicked links across eight months of monthly campaigns.
Cyber Aware pros:
- Monthly cadence runs itself — twelve months of varied campaigns from one setup
- Auto-enrolment turns every fail into a lesson without manual chasing
- Per-learner Human Risk Scores give leadership one number to track
- Per-seat pricing with no minimums, built for MSPs reselling under their own brand
Cyber Aware cons:
- Simulates AI voice scams inside email campaigns — it does not run live cloned-voice phone calls or deepfake video meetings
- Third-party review depth is thinner than the category giants
Verdict: Buy for teams up to a few hundred seats that need deepfake awareness running inside a managed monthly programme in 2026.
2. Hoxhunt: best for live deepfake video-meeting attacks
Hoxhunt's Voice Phishing Training puts employees on live practice calls, and its deepfake simulation routes users from a phishing email to a fake Teams, Meet or Zoom page where a cloned executive avatar — voice and video — urges action (Hoxhunt). Its reporting measures whether verification habits such as out-of-band callbacks hold up under authority pressure.
Hoxhunt pros: live voice plus cloned-avatar video; results feed a real-time risk score across email, SMS, voice and Teams; strong behavioural analytics.
Hoxhunt cons: the deepfake flow starts from a meeting invitation, so unsolicited inbound calls to the help desk are modelled differently; enterprise pricing is not published and rollout is heavier for small teams.
Verdict: Buy for enterprises with hundreds to thousands of staff and real deepfake exposure at the executive layer.
3. KnowBe4: best for teams already standardised on it
KnowBe4 added simulated vishing calls in 2026 alongside its existing callback phishing and deepfake training content (Cimento AI). Its library exceeds 1,000 modules in 35+ languages, and it holds the industry's largest phishing benchmark dataset.
KnowBe4 pros: deepest content library; mature enterprise reporting; benchmark data to compare click rates against peers.
KnowBe4 cons: deepfake coverage is content-led rather than live-call simulation; tiers and add-ons make total cost harder to predict than it looks.
Verdict: Hold if you already run KnowBe4 and can switch on the vishing capability; Skip as a deepfake specialist purchase on its own.
4. Resemble AI: best for voice-first simulation at scale
Resemble AI runs voice phishing scenarios — a spoofed customer call asking for account access, an AI-generated voicemail from a "CFO" — and assigns each employee a 0-100 risk score, with team and organisation analytics flagging high-risk behaviour. The company launched its Gen AI-based simulation platform for the public sector through Carahsoft in September 2025 (press release). Its deepfake incident database tracks reported fraud tied to deepfake attacks, which the company says now exceeds $2.6 billion globally.
Resemble AI pros: purpose-built voice engine rather than a bolt-on module; risk scoring per person; scales across thousands of unique simulations.
Resemble AI cons: voice-focused — pair it with an email-layer platform; enterprise conversations rather than self-serve pricing.
Verdict: Consider when voice is the dominant channel in your incident history.
5. Keepnet: best budget multi-channel option
Keepnet's Vishing Simulator uses AI-powered text-to-speech to run varied voice scenarios, and the platform covers email, SMS and voice in one tool (Keepnet). Teams get deepfake phishing education and verification drills without adding a second vendor.
Keepnet pros: multi-channel coverage in one subscription; AI text-to-speech varies the voice experience; approachable for smaller security teams.
Keepnet cons: voice simulations are scripted rather than live; less depth on deepfake video than Hoxhunt or Breacher.ai.
Verdict: Buy as the budget pick when one platform covering email, SMS and voice matters more than live deepfake realism.
6. Breacher.ai: best for red-team-grade deepfake engagements
Breacher.ai's OSES platform runs managed deepfake simulations: real-time voice clone calls impersonating executives, vendors or help-desk staff, with live deepfake avatars in Teams and Zoom. Clone time runs under five minutes, and every pretext is built from reconnaissance of your org chart and executive footprint rather than a template (Breacher.ai).
Breacher.ai pros: fully managed — no agents or software in your stack; board-ready findings in two to three weeks; recon-built pretexts.
Breacher.ai cons: engagement-based rather than an always-on platform; the wrong fit if you need monthly cadence at SMB scale.
Verdict: Consider for an annual or semi-annual deepfake red team alongside a continuous awareness programme.
How we ranked
Rankings weigh the six criteria above: voice realism, channel coverage, safe execution, auto-remediation, executive-ready reporting and self-running cadence. Claims about every vendor come from their public materials, linked with access dates above. Vendors whose deepfake capability is marketing-first rather than product-first did not make the list.
FAQ
What is a deepfake phishing simulation tool? A tool that recreates AI-generated voice and video attacks in a safe environment so employees practise the verification step — out-of-band callback, second approval — before a real deepfake reaches them.
How much damage can a deepfake attack cause? Arup lost $25 million in 2024 when a Hong Kong finance employee wired company funds after a video call in which every other participant was a deepfake.
Does Cyber Aware run live deepfake calls? No. Cyber Aware covers AI voice scams as phishing templates inside monthly campaigns with auto-enrolment and Human Risk Scores — the live-call and video-meeting tier belongs to Hoxhunt or Breacher.ai.
What is the difference between vishing and deepfake phishing? Vishing is voice phishing by phone; deepfake phishing adds an AI clone of a real person's voice or face to the same play. Simulation tools increasingly cover both.
How often should deepfake simulations run? Inside your monthly phishing cadence, with at least one live deepfake or voice scenario each quarter — the same auto-remediation flow as a normal campaign.
Which departments should be tested first? Finance and accounts payable first, then help desk and executive assistants — the roles a single mistake hurts most.
Are simulated deepfake attacks safe to run? Yes when the platform executes in a controlled environment: no credentials harvested, no real payments, every click landing on a branded explainer.
What one habit stops most deepfake fraud? Never act on payment or credential instructions from a call or video meeting — verify through a known number or channel that is not the one the request arrived on.
One last thing
The Arup employee suspected the first email. What defeated them was the video call. Whatever tool you buy, the control that matters is the verification habit — pick the tool that practises that habit under pressure, not the one with the most slides about AI.
