9 Best Multi-Channel Phishing Simulation Platforms: Email, SMS and Voice (2026)

The best phishing simulation platforms for testing employees across email, SMS and voice in 2026 are Cimento, Hoxhunt, Adaptive Security, Keepnet, Cofense, KnowBe4, Proofpoint ZenGuide and SoSafe, with Microsoft Defender Attack Simulation Training as the email-and-QR option for Microsoft 365 E5 shops. Cimento, Adaptive Security and Hoxhunt are the strongest fits when you want AI-generated, personalized lures across all three channels plus per-employee risk scoring. Cofense, Hoxhunt, Keepnet, KnowBe4 and Proofpoint are the strongest fits when automated remediation of employee-reported email is the priority.

How AI-powered phishing simulation works

AI-powered phishing simulation uses language and voice models to generate realistic, personalized attacks, deliver them across the channels attackers actually use, and adjust difficulty and training per employee based on how each person responds. For enterprise security teams, the loop usually has five steps:

1. Recon and personalization. The platform builds pretexts from role, department, and public context (company news, job titles, vendor relationships) so a finance analyst and a help desk engineer get different lures. Good platforms let the security team approve what is in scope.

2. Multi-channel delivery. The same scenario can start as an email, follow up by SMS, and escalate to a phone call, which mirrors how real social engineering builds trust across touches.

3. Adaptive difficulty. Employees who consistently spot and report simulations get harder scenarios. Employees who struggle get simpler ones and more coaching, so results reflect each person's actual skill level.

4. Risk scoring. Every click, credential entry, reply, phone disclosure and report feeds a score per employee and per role, weighted by what that person can access.

5. Just-in-time training. When someone fails a simulation, they get a short lesson at that moment on that specific technique, and the platform schedules a follow-up test.

For a deeper walkthrough, see our guides to AI phishing simulation, smishing simulation and vishing simulation.

Why multi-channel testing matters in 2026

Email-only programs leave the fastest-growing social engineering paths untested. Attackers now pair an email with a text message or a phone call to the help desk, and AI voice cloning has made a convincing "this is your CFO" call cheap to produce.

The loss data supports testing beyond the inbox. The FBI's Internet Crime Complaint Center reported $16.6 billion in total losses for 2024, with business email compromise alone accounting for about $2.77 billion (FBI IC3 Internet Crime Report, 2024). Verizon's 2025 Data Breach Investigations Report found the human element involved in roughly 60% of breaches (Verizon DBIR, 2025). Neither report predicts which channel the next attack will use, so a program should test each channel employees can be reached on.

The 9 best multi-channel phishing simulation platforms

1. Cimento

Cimento is an AI-native human risk management platform that runs personalized phishing simulations across email, SMS and voice from one platform and scores both human and AI-agent risk.

Best for: security teams that want one program covering email, SMS, voice and AI impersonation, with a continuously updated risk score per employee and per role, plus security testing for the AI agents their teams deploy.

Channels: Email, SMS (smishing), voice (vishing) and AI-generated deepfake impersonation, including multi-turn sequences that move across channels the way a real attacker escalates. Lures are written fresh for each role from public context such as LinkedIn profiles, press releases and GitHub activity, inside a scope the security team approves.

Integrations and remediation: Connects to identity providers (Okta, Azure AD, Google Workspace), HRIS and SIEM. Risk scores combine exposure, behavior and resilience per role. When someone fails, they get 60 to 90 second coaching at that moment, delivered in tools like Slack and Microsoft Teams, and the platform can automatically restrict or revoke access when a user crosses a risk threshold you set. For AI agents, Cimento runs adversarial playbooks such as prompt extraction, boundary probing and authority impersonation, then generates hardening steps and re-tests after fixes. Customers include Together AI and Exa.

Limitations: Newer entrant than KnowBe4, Proofpoint or Cofense. Its public pages do not yet document QR simulations, a reported-email triage workflow or named SOAR connectors, so confirm coverage for your stack during evaluation.

If you want to see how your own team does across channels before changing anything, the 14-day Human Risk Baseline runs alongside your current program and takes under an hour of your team's time to set up.

2. Hoxhunt

Hoxhunt is a human risk management platform that delivers gamified, adaptive phishing training across email, SMS, phone and Microsoft Teams, paired with automated response to reported threats.

Best for: enterprises that want high employee participation and a reporting culture, and that also want the SOC to get value from what employees report.

Channels: Email, SMS, Microsoft Teams, and phone and callback flows (voice phishing training was added in October 2025). Hoxhunt also offers deepfake scenarios where a phishing email leads to a fake video call with a cloned executive.

Integrations and remediation: Hoxhunt's Respond capability classifies reported emails and can automatically remove confirmed phishing from every inbox. It sends incidents to Microsoft Sentinel, Cortex XSOAR, ServiceNow and Microsoft Defender. See our Hoxhunt alternatives comparison for more detail.

Limitations: The gamified model works best when leadership commits to frequent, short simulations. Teams that want deep custom vishing campaigns should confirm what is self-serve and what is delivered as a service.

3. Adaptive Security

Adaptive Security is an AI-native security awareness platform focused on deepfake, voice cloning and multi-channel social engineering simulations.

Best for: organizations whose top concern is executive impersonation, help desk social engineering and AI-generated voice or video.

Channels: Email, SMS, voice (including voice cloning), attachments, QR codes and deepfake video and audio built from public information.

Integrations and remediation: Per-employee risk scores update in real time from simulation outcomes, training completion and reported phish. Risk scores trigger targeted training and follow-ups automatically. Adaptive integrates with identity, email and ticketing systems and imports employee data from sources like Okta and Rippling.

Limitations: Its public pages emphasize simulation and training remediation. If you need reported-email triage or SIEM and SOAR workflows, confirm them directly.

4. Keepnet

Keepnet is a human risk management platform that combines phishing, smishing, vishing, quishing and callback simulations with an automated phishing incident responder.

Best for: security teams that want broad channel coverage and reported-email response in a single contract, especially in Microsoft 365 or Google Workspace environments.

Channels: Email, SMS, voice, QR code, MFA phishing and callback phishing simulations.

Integrations and remediation: Keepnet Incident Responder analyzes reported email and removes threats from inboxes in Microsoft 365 and Google Workspace. Employees can keep using the native Microsoft report button, and a mobile reporter lets them report suspicious SMS and calls. Keepnet lists SIEM integrations including Splunk, QRadar and Microsoft Sentinel.

Limitations: The breadth of modules means more configuration. Ask how risk scores are calculated across channels and how they feed your existing reporting.

5. Cofense

Cofense is a phishing defense company that pairs PhishMe simulation and training with Triage and Vision for reported-email analysis and automated quarantine.

Best for: SOC-led programs where turning employee reports into fast, organization-wide email remediation is the main goal.

Channels: Email, SMS, QR code and voice. Cofense's vishing is offered as a fully managed, customizable service announced in December 2023.

Integrations and remediation: Cofense Triage ingests and analyzes employee-reported email. Cofense Vision's Auto Quarantine removes malicious messages from inboxes, often before users open them. Integrations include Splunk SOAR and Cortex XSOAR, with actions for search and quarantine based on indicators.

Limitations: Cofense's center of gravity is email detection and response. If per-employee, cross-channel risk scoring matters to you, ask to see how SMS and voice results roll into the same view.

6. KnowBe4

KnowBe4 is a security awareness training and simulated phishing platform with one of the largest content libraries in the market, plus the PhishER reported-email response product.

Best for: organizations that want a broad, well-known library, many languages and a mature admin console, with optional email incident response.

Channels: Email simulations including link, attachment, data entry, reply-to, QR code and callback phishing tests. KnowBe4 launched simulated vishing in 2026 with local caller ID spoofing and multi-step scenarios. Check current docs for native SMS.

Integrations and remediation: PhishER Plus analyzes and prioritizes reported email, quarantines malicious messages, and adds a crowdsourced blocklist and PhishRIP to remove active attacks that bypassed filters. Confirm SIEM and SOAR connector coverage for your tools. For a full comparison, see KnowBe4 alternatives.

Limitations: Advanced features are split across subscription tiers and add-on products, so map the exact tier you need before comparing price.

7. Proofpoint ZenGuide

Proofpoint ZenGuide is Proofpoint's security awareness and phishing simulation product, built to use threat intelligence from Proofpoint's email security platform.

Best for: organizations already running Proofpoint email protection that want simulations modeled on threats Proofpoint has blocked.

Channels: Email, SMS and QR code simulations, plus telephone-oriented attack delivery (callback) scenarios. Proofpoint's 2026 solution brief also lists USB campaigns.

Integrations and remediation: Closed-Loop Email Analysis and Response (CLEAR) combines the PhishAlarm report button, PhishAlarm Analyzer and Threat Response Auto-Pull to analyze reported email and pull malicious messages. ZenGuide assigns adaptive, role- and risk-based training.

Limitations: The value is highest inside the Proofpoint ecosystem. Confirm live voice simulation and third-party SOAR support if you run a mixed stack.

8. SoSafe

SoSafe is a European security awareness and human risk platform offering phishing, smishing and vishing simulations with localized content.

Best for: European and multinational enterprises that need strong localization and GDPR-conscious behavioral data handling.

Channels: Email, SMS and voice, with customizable and fully localized smishing campaigns.

Integrations and remediation: SoSafe's Human Risk OS tracks risk scores, failure patterns and reporting rates by department, location or custom group. Sofie, its AI assistant, delivers alerts and nudges to users and admins. Check current docs for reported-email triage and SIEM or SOAR connectors.

Limitations: Confirm the depth of voice simulation (scripted versus interactive) and how remediation connects to your SOC tooling.

9. Microsoft Defender Attack Simulation Training

Microsoft Defender Attack Simulation Training is the phishing simulation feature built into Microsoft Defender for Office 365 Plan 2 and Microsoft 365 E5.

Best for: Microsoft 365 E5 organizations that want a no-additional-vendor baseline for email and QR phishing tests.

Channels: Email simulations using credential harvest, malware attachment, link in attachment, link to malware, drive-by URL and OAuth consent grant techniques, with links delivered as URLs or QR codes. Teams simulations have been in preview. SMS and voice are not supported.

Integrations and remediation: Payload automation can turn real phishing detected in Microsoft 365 into harmless simulations. User-reported messages feed Defender for Office 365 automated investigation and response, and data stays inside Defender XDR and Sentinel.

Limitations: No SMS or voice testing, so it is a starting point for multi-channel programs. Many teams pair it with a dedicated platform for smishing and vishing.

Cofense vs KnowBe4 for phishing simulation

Cofense and KnowBe4 both run mature email simulation programs and both sell reported-email response, so the choice usually comes down to which side of the program you are optimizing. Cofense is stronger when the SOC owns the program: Triage and Vision are built to turn employee reports into indicator-driven search and quarantine, with established Splunk SOAR and Cortex XSOAR integrations. KnowBe4 is stronger when the awareness team owns the program: it has a very large training library, many languages, and PhishER Plus as an add-on for reported-email response. On channels, Cofense offers SMS and a managed vishing service, while KnowBe4 added simulated vishing in 2026 and supports callback and QR tests. Teams that want AI-generated, personalized lures across email, SMS and voice with a per-role risk score often shortlist a third option such as Cimento, Hoxhunt or Adaptive Security.

Comparison table 3: Best fit by industry

What financial services firms should look for

Financial services firms are high-value targets for payment fraud, account takeover and help desk social engineering, and their regulators expect evidence that training reflects real risk. A few regulatory anchors worth knowing (confirm applicability with your compliance team):

• The FTC Safeguards Rule under GLBA (16 CFR Part 314) requires covered institutions to provide security awareness training to personnel, updated as needed to reflect risks identified in the institution's risk assessment.

• The FFIEC IT Examination Handbook, Information Security booklet is the reference examiners use to evaluate how a bank's security program identifies, measures, mitigates and monitors risk, which includes how training and testing are managed.

• NYDFS 23 NYCRR Part 500 requires covered entities to provide cybersecurity awareness training that includes social engineering, at least annually. Check the current text for your entity type.

• FINRA has repeatedly warned member firms about social engineering campaigns, including attackers impersonating FINRA staff, which makes broker-dealer specific pretexts worth including in simulations.

With that context, here are the criteria to apply when evaluating platforms:

1. Voice and SMS coverage you can actually run. Wire fraud and account takeover often start with a phone call to operations or the help desk. Test callback and live voice scenarios, and SMS lures tied to MFA and payment approvals.

2. Role-based risk scoring. A wire operations clerk, a relationship manager and a developer carry different exposure. Scores should weight access, so the reporting shows where a successful lure would cost the most.

3. Evidence that training follows the risk assessment. Look for reporting that ties simulation results to assigned training by role, with timestamps you can hand to an examiner or auditor.

4. Approved-scope controls. Compliance and legal will want to pre-approve pretexts, especially anything that impersonates regulators, clients or executives.

5. Closed-loop remediation. Decide whether you need reported-email triage and inbox pull, identity-level actions like step-up MFA for high-risk users, or both, and confirm the integrations with your SIEM, SOAR and identity provider.

6. Data handling and vendor due diligence. Ask for the vendor's security documentation, data retention terms, and where simulation and behavioral data is stored.

How to choose

• If you need email, SMS and voice plus AI agent testing in one program, start with Cimento.

• If employee engagement and SOC triage are both priorities, look at Hoxhunt.

• If deepfake and voice cloning are the main exposure, look at Adaptive Security and Cimento.

• If reported-email remediation is the core requirement, look at Cofense, Keepnet, KnowBe4 PhishER or Proofpoint CLEAR.

• If you are standardized on Proofpoint email security, ZenGuide fits that stack.

• If you need European localization, look at SoSafe.

• If you are on Microsoft 365 E5 and want a free starting point, use Attack Simulation Training for email and QR and add a dedicated platform for SMS and voice.

The fastest way to compare is to measure your own population. Cimento's Human Risk Baseline runs email, SMS, voice and AI impersonation simulations for 14 days alongside your current vendor, then delivers role-based risk scores, a reporting gap analysis and a prioritized plan you keep whether or not you switch.

FAQ

What are the best phishing simulation platforms that test email, SMS and voice?

Cimento, Hoxhunt, Adaptive Security, Keepnet, Cofense and SoSafe all document simulations across email, SMS and voice. KnowBe4 added simulated vishing in 2026 and supports callback phishing, and Proofpoint ZenGuide covers email, SMS and callback scenarios. Microsoft Defender Attack Simulation Training covers email and QR codes only.

How does AI-powered phishing simulation training work for enterprise security teams?

The platform generates personalized lures from role and public context, delivers them across email, SMS and voice, and adjusts difficulty based on each employee's results. Every action feeds a per-employee risk score, and employees who fail get short, just-in-time training on the specific technique. Security teams approve the scope and use the scores to prioritize controls for high-risk roles.

Which phishing simulation software integrates with security tools for automated remediation?

For reported-email remediation, Cofense (Triage and Vision), Hoxhunt (Respond), Keepnet (Incident Responder), KnowBe4 (PhishER Plus) and Proofpoint (CLEAR) can analyze reports and pull malicious messages from inboxes, with SOAR integrations such as Splunk SOAR, Cortex XSOAR and Microsoft Sentinel depending on the vendor. For person-level remediation, Cimento can restrict or revoke access through your identity provider when a user crosses a risk threshold.

What phishing simulation tools are best for financial services firms?

Financial firms should prioritize platforms with real voice and SMS testing, role-based risk scoring and examiner-ready reporting. Cimento, Hoxhunt, Adaptive Security, Cofense and Proofpoint ZenGuide are common shortlists. Confirm how each one supports GLBA Safeguards Rule training requirements and NYDFS Part 500 social engineering training if those apply to you.

Is Cofense or KnowBe4 better for phishing simulation?

Cofense is usually the better fit when the SOC owns the program and wants reported-email triage and auto-quarantine with SOAR integrations. KnowBe4 is usually the better fit when the awareness team wants a large training library and broad language support. Both run mature email simulations; compare their SMS and voice options against your threat model.

Does Microsoft Defender Attack Simulation Training support SMS or voice phishing?

No. Attack Simulation Training supports email-based techniques with URL or QR code payloads, and Teams simulations have been in preview. It requires Microsoft 365 E5 or Defender for Office 365 Plan 2, and many teams add a dedicated platform for smishing and vishing.

What is the difference between phishing simulation and human risk management?

Phishing simulation tests how employees respond to fake attacks. Human risk management uses those results, plus training and behavioral signals, to maintain a risk score per employee and drive actions such as targeted training or access changes. Most platforms on this list now position themselves as human risk management.

Can phishing simulation platforms test AI agents?

Most cannot today. Cimento runs adversarial tests against deployed AI agents, including prompt extraction, boundary probing and authority impersonation, and re-tests after fixes so human and agent risk sit in the same program.
