Best Multi-Channel Phishing Test Tools (2026): Email, Voice, SMS, Deepfake

In early 2026, a wave of attacks on US law firms followed the same script. An employee received an invoice-themed email. Then the phone rang. The caller said he was from internal IT, referenced the email, and walked the employee through "verifying" the issue by installing a remote support tool. From there the attacker had a live session, pulled documents, and started an extortion clock. According to Mandiant's reporting on the group tracked as UNC3753, the whole sequence could run inside a single business day.

The email was the easy part to catch. The phone call was the part that worked. If your phishing program only tests employees on email, you are rehearsing them for the move the attackers expect them to block, and leaving the move that actually breaches them untouched. The same pattern shows up across 2026's biggest social engineering campaigns: the ShinyHunters cluster reportedly used voice calls, not email, to talk employees out of their single sign-on credentials before pivoting into corporate SaaS.

That is the case for multi-channel phishing testing. The tools below are ranked by the channels they genuinely simulate, and by how real that simulation is. Those two questions sort the market faster than brand size or template count, because most "phishing simulation" products are still email-first and bolt the other channels on later, if at all.

What "multi-channel phishing testing" actually means

A multi-channel phishing test tool simulates social engineering across more than one delivery channel and, ideally, lets you coordinate them. The channels that matter in 2026 are:

• Email phishing: the baseline every tool covers.

• Vishing: voice phishing over a phone call.

• Smishing: phishing over SMS or messaging apps.

• Quishing: QR-code lures that move the victim onto a personal device.

• Deepfake video: AI-generated video impersonation of a real person, usually an executive.

Listing the channels is the easy part. The harder question, and the one most buyer guides skip, is what a vendor actually ships behind each label. Two distinctions decide whether a tool is genuinely multi-channel or just multi-channel in marketing.

The first is live versus scripted voice. "Vishing simulation" can mean a live, adaptive AI agent that calls an employee, holds a real conversation, handles objections, and applies a chosen social engineering tactic. It can also mean a recorded voicemail dropped into a mailbox, or a text-to-speech message read from a template. All three get filed under "vishing" in feature lists. Only the first rehearses the experience employees face when a confident human voice pushes back on their hesitation.

The second is coordinated versus separate. Real attackers chain channels in one operation, like the email-then-call sequence above. Some platforms can run a single hybrid campaign where the call and the email reference each other and report as one event. Others can send an email campaign and a voice campaign, but they are two disconnected exercises that you stitch together manually. The hybrid workflow is the one that mirrors how 2026 intrusions actually unfold.

It helps to see this as three generations of "realistic." Early simulations (roughly 2010 to 2018) were convincing-looking branded emails. The next wave (2018 to 2023) added OSINT personalization, so the email referenced your role, your tools, your manager. The current generation extends past the inbox into live voice, cloned voices, deepfake video, and coordinated hybrid attacks. This is why a large, mature, email-first incumbent can score well overall and still rank low for multi-channel specifically. It is excellent at a generation the attackers have already moved past.

This is not a theoretical risk. Verizon's 2026 Data Breach Investigations Report attributes the human element to a majority of breaches, and ENISA's 2025 threat landscape puts social engineering at roughly 60 percent of observed initial access. Studies on AI-generated spear phishing have measured click-through rates competitive with human-written attacks at a fraction of a cent per message. The cost of producing convincing multi-channel lures has collapsed, and testing has to keep up.

How to evaluate a multi-channel phishing test tool

Before the list, here is a compact set of criteria to score tools against. Weight them by the threats your organization actually faces, not by which vendor has the longest feature page.

• Channel coverage. Which of email, vishing, smishing, quishing, and deepfake video does it simulate? Map this against the channels in your own incident history.

• Live versus scripted vishing. Does it place a live, adaptive AI call, or only drop a voicemail or play a text-to-speech script? This is the single biggest differentiator in the category.

• Hybrid coordination. Can it run a call and an email as one coordinated campaign that reports together, or are they separate exercises?

• OSINT personalization. Does it tailor scenarios using role, department, and other profile data? This is close to table stakes now, so look at how rich and how automated it is.

• Deepfake as a simulation, not just content. A real test sends an employee a deepfake call or video and measures the response. Many "deepfake" features are awareness lessons that teach people deepfakes exist. Those are different products.

• Admin safety controls. Preview-before-launch lets you see exactly what an employee will experience. A cooling period prevents hammering the same person repeatedly. Difficulty mapped to a recognized scale, such as the NIST Phish Scale, keeps campaigns calibrated rather than arbitrary.

• Point-of-error training. The most robustly supported finding in the training literature, across a 2024 meta-analysis of 42 studies, is that coaching delivered at the moment someone fails reduces susceptibility by around 40 percent. Favor teachable-moment redirects over manager escalation or public shaming.

• Reporting and human risk depth. Can it show trends over time and roll up to board-level risk views? Larger suites lead here; specialists are often lighter.

• Compliance and data residency. EU buyers under NIS2 and DORA, and anyone with GDPR obligations, should check data residency and how behavioral data is handled, especially for voice recordings.

• Price and scale fit. A 150-person company and a 50,000-seat enterprise have different definitions of "manageable." Match the operational overhead to your team.

Two cautions belong in any honest evaluation. Cloning a real executive's voice for a simulation raises consent questions that are still unsettled in several jurisdictions, particularly under EU law, so confirm how a vendor handles authorization. And real outbound vishing and smishing run into telecom regulations that vary by region and can constrain what you are allowed to send. Ask vendors how they handle both. For a deeper walk through building a program across channels, Brightside's multi-vector training guide is a useful companion to this comparison.

The best multi-channel phishing test tools for 2026

The list is ordered by genuine multi-channel coverage and simulation realism, not by company size. Feature claims reflect what vendors document publicly as of mid-2026; verify the specifics that matter to you in a live demo, because this category ships quickly and several capabilities sit in a partial or undocumented state.

Brightside AI: Best for multi-channel realism in one platform

Brightside is designed to rehearse the attacks employees will actually face, across the channels attackers actually use, inside one product. Its strongest piece is the vishing simulator, which places a live outbound AI call rather than a voicemail or a text-to-speech read. Admins can configure a caller persona, let the system generate an opening line and recommend a social engineering strategy, and assemble tactics such as authority, urgency, reciprocity, and pretexting. Voices can be cloned from a one to two minute recording for executive-impersonation scenarios, and there are preset voices in English, French, German, and Italian.

The capability that maps most directly onto 2026 intrusions is the hybrid attack: a phone call and a trackable phishing email run as a single coordinated workflow, the same one-two sequence that broke the law firms above. Per Brightside's feature comparison, several of its controls are unusual in the market, including the AI-recommended attack strategy, the social engineering tactic builder, and a preview-before-launch mode that lets an admin experience the simulation in the browser before anyone is targeted. Difficulty is mapped to the NIST Phish Scale, and a cooling period prevents the same lure from hitting the same employee repeatedly. Deepfake video simulation and OSINT-personalized spear phishing round out the channel coverage. The Swiss base and multilingual support fit European buyers weighing NIS2 and DORA obligations.

Pros:

• Live, adaptive AI vishing with configurable persona, tactics, and voice cloning

• Coordinated hybrid voice-plus-email campaigns in a single workflow

• Strong admin safety controls: preview-before-launch, cooling period, NIST Phish Scale difficulty

• Deepfake and OSINT spear-phishing coverage; EN/FR/DE/IT and EU-friendly positioning

Cons:

• Specialist simulation depth rather than a broad human risk management suite

• Lighter on board-level risk scoring than the large incumbents

• Built-in courses are scripted content, not live AI tutoring

Best for: Teams that want the most realistic voice and hybrid attack rehearsal, with deepfake and email in the same platform, and European organizations that value data residency and multilingual delivery.

Adaptive Security: Best for AI-threat coverage across every channel

Adaptive Security positions itself around AI-era threats and covers email, SMS, voice, and deepfake video, with heavy use of OSINT to generate scenarios that mirror how attackers research a target. Its content leans into newer risks, including prompt-injection and AI-tool abuse, which makes it a strong fit for organizations whose threat model is specifically about sophisticated, AI-assisted adversaries.

The company markets itself as the only platform unifying email, vishing, smishing, and deepfake in one interface. In practice, multi-channel coverage is now shared by several vendors on this list, so treat that as a strong product rather than a unique one, and compare the depth of each channel directly. Adaptive's breadth comes with a heavier deployment and a steeper administrative learning curve than simpler tools.

Pros:

• Genuine coverage across email, SMS, voice, and deepfake video

• Deep OSINT-driven scenario generation and AI-threat-specific content

• Strong fit for organizations focused on advanced, AI-assisted attackers

Cons:

• "Only unified platform" framing overstates how rare multi-channel coverage now is

• More complex to deploy and administer than lightweight options

Best for: Enterprises whose primary concern is AI-era and executive-impersonation threats, and who can resource a feature-rich platform.

Jericho Security: Best for AI-generated scenario variety

Jericho leans on generative AI to write novel phishing pretexts on demand rather than selecting from a fixed template library, and it offers live adaptive vishing and deepfake video. For teams that want maximum scenario variety and dislike the maintenance burden of a template catalog, the generative approach is appealing because it rarely repeats itself.

The flip side is that generative output needs guardrails to stay on-message and on-brand, and Jericho's operational workflow is less documented publicly than some peers. Confirm how campaigns are reviewed and controlled before launch.

Pros:

• Generative AI produces high scenario variety without library upkeep

• Live adaptive vishing and deepfake video coverage

• Good fit for teams wanting fresh, non-repeating content

Cons:

• Generative content requires guardrails and review

• Operational details less documented than some competitors

Best for: Teams that prioritize scenario freshness and AI-generated variety across channels.

Arsen: Best for European, simulation-first programs with SMS

Arsen is a Paris-based, simulation-first platform covering email phishing, smishing, and vishing, with synchronized hybrid attacks that combine an AI call and a phishing email. It can fold breach and dark-web exposure data into scenarios, so a simulation can reference real credential exposure rather than a generic pretext, which raises the realism for organizations that have appeared in known leaks.

Arsen is less covered in English-language buyer research than the larger names, and details such as the exact mechanics of voice cloning and the single-workflow hybrid are worth confirming directly. For any feature that is decisive in your evaluation, vendor verification is the right move.

Pros:

• Email, SMS, and voice coverage with synchronized hybrid attacks

• Breach and dark-web data can inform scenario realism

• Strong European, simulation-first positioning

Cons:

• Thinner English-language buyer documentation

• Verify voice-cloning and hybrid-workflow specifics directly

Best for: European security teams that want a simulation-first tool with solid SMS coverage and exposure-informed scenarios.

Keepnet Labs: Best for the widest channel checklist plus response

Keepnet is a broad human risk management platform that ticks the most channel boxes on a procurement checklist: phishing, vishing, smishing, QR-code quishing, and callback scenarios, with a vishing-specific metrics dashboard and strong localization and compliance reporting. It also extends past simulation into phishing response and incident workflows, which appeals to teams that want testing and response in one place.

The caveat is on the voice channel. Keepnet's vishing uses AI text-to-speech with template-based scenarios rather than a fully unscripted live conversation, so it covers the channel without matching the realism of a live adaptive call. If breadth and reporting matter more than conversational voice realism, that trade can be the right one.

Pros:

• Widest channel checklist: email, voice, SMS, QR, callback

• Vishing metrics dashboard plus response and incident workflows

• Strong localization and compliance-oriented reporting

Cons:

• Vishing is template and text-to-speech, not live adaptive conversation

• Breadth can mean less depth on any single channel

Best for: Teams that want the broadest channel coverage and built-in response workflows in one compliance-friendly platform.

SoSafe: Best for EU compliance-driven, behavior-science awareness

SoSafe is a European, behavior-science-driven awareness and human risk platform with strong regional scale, EU data residency, and GDPR alignment. On the multi-channel axis it offers template-based vishing with built-in deepfake voice cloning and smishing, layered onto a mature awareness program with manager workflows and compliance breadth.

Like several awareness-led suites, SoSafe's vishing is not a live outbound call, and simulation depth sits behind the platform's awareness and risk-management features in emphasis. For organizations whose buying decision is anchored in EU compliance and culture change, that ordering of priorities can be exactly right.

Pros:

• Strong EU scale, data residency, and GDPR alignment

• Behavior-science content with manager workflows and compliance breadth

• Smishing plus template vishing with deepfake voice cloning

Cons:

• Vishing is not a live outbound call

• Simulation realism is secondary to awareness and risk-management breadth

Best for: EU enterprises prioritizing compliance, data residency, and behavior-change programs over raw simulation realism.

Hoxhunt: Best for continuous, adaptive programs at scale

Hoxhunt is an enterprise human risk platform known for adaptive difficulty that tunes itself to each user, gamified micro-training, and remediation that connects into security operations. It reports strong behavior-change outcomes; the company has stated that adaptive training cut repeat phishing victims by around 63 percent within six months, a vendor-reported figure worth validating against your own baseline.

On channels, Hoxhunt covers email and offers a browser-based fake video-meeting simulation that combines an email with a simulated Teams, Meet, or Zoom call. That is a useful step beyond the inbox, but it is not a live outbound phone call, and voice and SMS coverage is thinner than the dedicated multi-channel tools. Hoxhunt's strength is sustaining engagement and measurable change across a large workforce over time.

Pros:

• Adaptive difficulty and gamified micro-training drive engagement

• SOC-connected remediation and strong reporting at enterprise scale

• Browser-based video-meeting simulation extends past plain email

Cons:

• Video simulation is browser-based, not a live outbound call

• Voice and SMS coverage thinner than dedicated multi-channel platforms

Best for: Large organizations that want a continuous, adaptive program optimized for engagement and long-term behavior change.

KnowBe4: Best for breadth, scale, and a mature content library

KnowBe4 is the most widely adopted platform in the category, with a template library running into the thousands across many languages, mature automation through its AIDA agent, and deep compliance content. It is the safe, proven choice for running large-scale email programs, and it covers QR-code and SMS scenarios. The company reports phish-prone percentages dropping by up to 86 percent over 12 months of training, a KnowBe4 benchmark figure to read as vendor-reported.

The gap is voice. KnowBe4's vishing consists of voicemail simulations on its Gold tier and inbound callback phishing on its Diamond tier, neither of which is a live outbound AI conversation. For multi-channel realism specifically, it trails the specialists, and keeping simulations realistic tends to be administratively intensive. If you already run KnowBe4 and want to extend into live voice, it is worth reviewing how the dedicated voice platforms compare; roundups of KnowBe4 alternatives lay out the options.

Pros:

• Largest template library and broadest language coverage

• Mature automation, compliance content, and proven scale

• Covers email, QR, and SMS scenarios

Cons:

• No live outbound AI vishing; voice is voicemail or inbound callback only

• Keeping simulations realistic is administratively heavy

Best for: Organizations that prioritize content breadth, language coverage, and a proven platform for large email-led programs.

Proofpoint: Best for existing Proofpoint ecosystem shops

Proofpoint's simulation strength comes from its threat intelligence. Because it ingests live phishing data from its email-security stack, its Satori capability can deploy simulations modeled on the threats actually hitting your organization, which is hard to match if you are already a Proofpoint customer. It covers email and smishing plus USB-based scenarios, and uses its own Phish Hooks difficulty methodology rather than a NIST-labeled scale.

Standalone, and specifically for voice and deepfake, Proofpoint is weaker than the multi-channel specialists, and much of its value is unlocked by the broader ecosystem. For shops already standardized on Proofpoint, that integration is the whole point.

Pros:

• Threat-intel-fed simulations modeled on real attacks hitting you

• Strong value when integrated with the wider Proofpoint stack

• Email, smishing, and USB scenario coverage

Cons:

• No live AI vishing or deepfake video simulation

• Most value depends on already owning the ecosystem

Best for: Organizations already invested in Proofpoint that want simulations driven by their own live threat intelligence.

A note on email-only and open-source tools

Open-source and email-only tools such as GoPhish still have a place. They are inexpensive, transparent, and fine for basic email click-testing or for a small team getting a program off the ground. What they cannot do is rehearse anything beyond the inbox. There is no live voice, no SMS, no deepfake, and no coordinated hybrid attack, which caps them at the first generation of realism. Treat them as the floor the multi-channel platforms are built to rise above, not as a substitute when voice and video are part of your real threat picture.

Multi-channel coverage at a glance

The table summarizes documented coverage as of mid-2026. "Partial" means the channel exists in a limited form, such as voicemail or text-to-speech rather than a live call, or a separate campaign rather than a coordinated workflow. Treat it as a starting point and confirm specifics in a demo.
