KnowBe4 serves over 70,000 organizations and has the largest phishing template library in the industry. If you have never run a phishing simulation program before, KnowBe4 gets you started fast. That is its real value.

The problem is what the threat landscape looks like now.

Real attackers in 2026 do not use templates. They scrape your employees' LinkedIn profiles, read their recent posts, note their job titles and departments, check what industry events they just attended, and write a phishing email that references something personal and specific. Hoxhunt's 2026 Phishing Trends Report recorded a 14x surge in AI-generated phishing over the holidays. Mandiant's M-Trends 2026 report identified vishing (voice phishing) as the second most common initial access method across all incident response investigations. North Korea's threat actors spent six months social engineering specific signers at Drift Protocol before draining $285 million in twelve minutes.

If your employees are only tested against generic templates, they are trained for the attack that happened in 2019, not the one coming at them today.

This comparison breaks down exactly how KnowBe4 and NexGuards differ, where each product wins, and which one fits your team.

The Core Difference

KnowBe4 asks: how many templates can we run against your employees?

NexGuards asks: how does a real attacker target your specific employees, and how do we make training stick the moment they fail?

That difference shapes everything, from how attacks are generated to what happens in the thirty seconds after an employee clicks a link.

KnowBe4: What It Does Well

KnowBe4 has been in the market long enough to accumulate advantages that are genuinely hard to replicate.

The template library is enormous. Over 15,000 phishing templates, including "Current Events" templates that get refreshed as news breaks. You can find a template for almost any scenario, and their AIDA AI system now selects templates based on each user's historical performance, so employees who have clicked before get progressively harder tests.

In December 2025, KnowBe4 launched a deepfake awareness feature. Admins upload a short video or audio clip of an executive, and the platform generates awareness training content showing employees what a deepfake looks and sounds like. It is an education tool, not a simulation attack, but it is useful for organizations that want to introduce employees to the concept.

Vishing simulation is available from the Gold tier. The platform places outbound calls from a scripted library, which covers the basic case of testing whether employees will give credentials over the phone.

KnowBe4's integrations are mature. It connects to Microsoft 365, Google Workspace, Slack, SIEM platforms, and most HR systems. For large enterprise IT teams that need to plug into existing workflows, this is a real advantage.

Compliance reporting is strong. KnowBe4 has been SOC 2 audited, and its reports are accepted by most enterprise compliance teams. If your primary goal is showing auditors that you run a security awareness program, KnowBe4 covers that.

Where KnowBe4 falls short:

Template-based phishing does not prepare employees for real attacks. No template knows that your finance manager just posted about attending an ACH conference. No template knows your CFO's name and writing style. No template references last Tuesday's company all-hands meeting. Real attackers use all of this, and they automate it at scale.

KnowBe4's deepfake feature shows employees what deepfakes look like. It does not simulate a deepfake attack landing in their inbox or call. Knowing what something looks like is not the same as having been tested against it under realistic conditions.

Vishing simulation is scripted from a library. It is not personalized to the individual employee being called.

NexGuards: What It Does Differently

NexGuards was built on the premise that the only way to prepare employees for real attacks is to run real-quality attacks against them.

How the personalization works:

Before sending a phishing email, NexGuards scrapes the target employee's full LinkedIn profile, including their last five published posts, their stated job title, department, work history, and skills. It also factors in contextual events tied to their industry calendar, holidays relevant to their location (Ramadan for a Dubai-based team, Thanksgiving for a US organization), and company-specific information like department names and reporting structure.

The result is a phishing email that references something the employee actually cares about, written in a way that mirrors how a real attacker would approach them. The difference in click rates between generic templates and OSINT-personalized attacks is not incremental. It is significant.

Attack vectors:

NexGuards runs phishing simulations across four channels, all in one platform:

Email phishing (OSINT-personalized)
Vishing: outbound voice calls
Smishing: SMS text message attacks
Fake video meetings: simulated Google Meet, Zoom, and Microsoft Teams calls that use cloned executive voices (deepfake audio, no video)

The fake meeting channel is worth explaining. An employee receives a calendar invite from what appears to be a legitimate internal meeting. They join. They hear a voice that sounds exactly like their CEO or direct manager. They are asked to approve a wire transfer, share their credentials, or click a link in the chat. If they do, the session is captured as a simulated compromise.

KnowBe4 does not currently simulate this attack vector. Neither does Proofpoint. It is one of the fastest-growing real-world attack types and most organizations have never tested their employees against it.

What happens after an employee clicks:

This is where the training approach diverges most sharply from every competitor.

The moment an employee clicks a phishing link or falls for a voice or meeting attack, two things happen:

First, a microlesson opens in their browser immediately. It shows them the exact attack they just fell for, with every red flag annotated. The phishing email is displayed with markers pointing to the suspicious sender domain, the mismatched link URL, the urgency language, the impersonation tactic used. The employee sees, in real time, exactly how they were tricked.

Second, they receive an email with a link to revisit the lesson, in case they want to review it again on their own time.

The reason this matters: research on learning retention consistently shows that the strongest retention happens at the moment of failure, when the lesson is directly tied to an experience the person just had. Annual security videos are forgotten within a week. A lesson that arrives thirty seconds after you just got phished is not forgotten.

Gamification:

NexGuards includes a full gamification system. Employees earn points for correctly identifying and reporting phishing attempts. Leaderboards let employees see how they rank against colleagues. Badges are awarded for milestones. The competitive dynamic changes the relationship employees have with security training: instead of something done to them once a year, it becomes a game they can win.

Hoxhunt has built their entire product around this idea. The difference is that NexGuards combines gamification with OSINT-personalized, multi-vector attacks and immediate contextual training. Engagement and realism in the same platform.

Reporting:

Security teams get per-employee risk scores that update with each simulation. The scores show which employees are high-risk, which departments are weakest, and how the organization's posture is changing over time. Compliance reports can be exported for auditors, showing simulation coverage, training completion, and risk trend data.

Who Should Use KnowBe4

KnowBe4 makes sense if:

You need a compliance-first program that checks the box for auditors with minimal configuration
You have a large enterprise with complex integration requirements and an established security awareness program you want to maintain
You are starting from zero and need a huge template library to get going quickly
Your employees are relatively unsophisticated and generic templates still produce meaningful click rates

KnowBe4 has served hundreds of thousands of organizations well in an era when template-based attacks were the norm. For organizations where the threat model is still "someone sends a generic phishing email," KnowBe4 is adequate.

Who Should Use NexGuards

NexGuards makes sense if:

Your employees are targeted by real attackers who do reconnaissance before attacking
You need to test employees against voice, SMS, and fake video meeting attacks, not just email
You want training that actually changes behavior, not just compliance completion rates
Your organization has a global workforce that includes Arabic-speaking employees
You need to prove to your board that your training program prepares employees for current threats, not 2018-era attacks
You want employees engaged with security training through competition and gamification, not mandatory annual completions

The Honest Assessment

KnowBe4 is a mature product that does exactly what it says on the box. If your goal is to run a phishing awareness program that satisfies auditors and gives your security team a defensible answer when asked "what are you doing about phishing," KnowBe4 gets you there.

The problem is that the threat landscape has moved past what KnowBe4 tests for.

Real attackers personalize at scale using OSINT and AI. They call employees and clone executive voices. They send calendar invites to fake meetings. They send SMS messages timed to industry events. KnowBe4's December 2025 deepfake feature teaches employees to recognize deepfakes in a classroom setting. It does not test whether they can resist a live deepfake voice on a call when they have thirty seconds to decide whether to approve a payment.

NexGuards was built to test exactly that. The trade-off is a smaller template library and fewer enterprise integrations than a company that has been building for fifteen years. If you need the biggest possible template catalog or are locked into a complex vendor integration, KnowBe4 still wins on those dimensions.

If you need to know whether your employees can withstand a real attack from a well-resourced adversary, the choice is clear.

NexGuards is a cybersecurity awareness and phishing simulation platform built for the age of AI-generated, OSINT-personalized attacks. To see a live demo with a phishing email generated from a real LinkedIn profile, contact the NexGuards team.
