KnowBe4 Alternatives: What to Know When Evaluating Platforms (and Why There Is No Equal)

The cybersecurity market includes platforms addressing phishing, email security and emerging AI risks. As the digital workforce expands to include both people and AI agents, organizations need to determine whether individual solutions can protect a broader attack surface.

This guide breaks down what to look for when comparing KnowBe4 alternatives and where specialized platforms may differ from KnowBe4’s broader digital workforce security approach.

Key Takeaways

• Attack simulation and training should address evolving, multi-channel social engineering while adapting to individual behavior and risk.
• Email and collaboration security should protect against inbound threats and outbound data loss across email, messaging and other collaboration environments.
• Agent security provides visibility and control over AI agents, including shadow AI, while addressing risks such as prompt injection and sensitive data exposure.
• Specialized KnowBe4 alternatives may provide strong capabilities in individual areas, but organizations seeking coverage across all three categories may need multiple solutions.
• KnowBe4 connects attack simulation and training, email and collaboration security and agent security within one platform.

What Is KnowBe4?

KnowBe4 is a digital workforce security platform designed to protect both humans and AI agents. The platform spans three core areas: attack simulation and training, email and collaboration security and agent security.

These pillars provide a useful framework for comparing alternatives, as social engineering attacks span email, messaging, phone calls and emerging formats such as video. KnowBe4’s 2026 Phishing Threat Trends Report Vol. 7 found that 86% of analyzed phishing attacks were AI-driven, while Microsoft Teams attacks increased 41% and calendar invite phishing rose 49% over six months.

KnowBe4 addresses these threats with attack simulation tests, personalized training content, collaboration security and dedicated AI agent security.

This breadth matters when comparing platforms. A vendor may offer an alternative to one KnowBe4 capability without offering comparable coverage across the other areas.

How KnowBe4 Alternatives Compare for Attack Simulation and Training

Social engineering attacks increasingly span channels beyond email. KnowBe4’s 2025 Phishing Threat Trends Report found a 449% increase in vishing and a 38% increase in attacks that bypassed secure email gateways.

When comparing KnowBe4 attack simulation and security awareness training alternatives, assess whether solutions provide realistic, multi-channel simulations and adaptive training that reflect changing threats and individual risk.

What To Look for in Attack Simulation and Training

Effective attack simulation should incorporate behavioral signals from the employees being tested. Completion and click rates provide useful benchmarks, but they do not show the full picture of individual risk or what intervention a specific employee needs.

When evaluating platforms, look for:

• Realistic social engineering and phishing simulations
• Coverage across multiple attack types and channels
• Personalized and adaptive training
• A frequently updated content library across formats, topics and languages
• Custom content creation
• Automation and orchestration
• Behavioral intelligence
• Individual risk measurement
• Evidence of behavior change and risk reduction

Where KnowBe4 Alternatives May Fall Short

KnowBe4 alternatives may address specific security awareness needs, but training-focused platforms can fall short when organizations require capabilities beyond traditional training.

• Hoxhunt: Its phishing-centric approach may provide less coverage for organizations seeking broader multi-channel attack simulation and security beyond training.
• Infosec IQ: Organizations may need greater depth in behavioral intelligence and individual risk visibility alongside its training and simulation capabilities.
• NINJIO: A training-led approach may leave organizations needing additional capabilities for advanced simulation, automation and individual risk measurement.

These differences matter as security awareness expands beyond training employees to understand their individual risk.

Other phishing and email security alternatives extend into threat detection and response, but have different limitations.

• Cofense: Its emphasis on phishing may leave gaps for organizations that need protection and training across a wider range of attack channels.
• Proofpoint: Buyers should assess how closely its email security controls connect with personalized learning and broader workforce security.
• Microsoft Attack Simulation Training: Because it operates within the Microsoft security ecosystem, organizations should consider whether it provides the flexibility and visibility they need across a more varied technology stack.

Buyers should compare how each handles personalized learning, orchestration, behavioral risk visibility and protection across different channels and security environments.

How KnowBe4 Approaches Attack Simulation and Training

KnowBe4 uses realistic, multi-channel attack simulations to prepare employees for changing social engineering tactics. AI Defense Agents (AIDA) generate simulations and automate campaigns based on threat changes and user risk.

Training then adapts to the individual. Behavioral intelligence and KnowBe4’s proprietary Risk Score help identify where risk is highest, while AIDA delivers targeted training and knowledge refreshers based on those signals.

Organizations can supplement training with KnowBe4 Studio’s continuously updated content library or create custom content for their own policies and risks.

Together, these capabilities have helped make KnowBe4 the #1 security awareness training platform on G2 for more than six years. The result is also measurable behavior change: KnowBe4’s 2026 Phishing by Industry Benchmarking Report found that the average Phish-prone Percentage (PPP) fell from 33.2% before training to 4.2% after 12 months of continuous training and testing.

How KnowBe4 Alternatives Compare for Email and Collaboration Security

Training cannot prevent every employee from encountering a convincing social engineering attack, so organizations also need technical controls. That protection increasingly needs to cover messaging and collaboration channels in addition to email.

When evaluating platforms, consider how well they connect threat detection and response with employee reporting, behavioral context and threat intelligence across those environments.

What to Look for in Collaboration Security

Strong collaboration security protects against inbound threats and outbound data loss across the communication channels employees use every day.

It should also connect technical defenses with employee reporting so security teams can identify and respond to suspicious activity across email, messaging and collaboration environments.

Solutions should provide:

• Email threat detection
• Phishing, impersonation, and business email compromise (BEC) protection
• User-reported threat analysis
• Intelligent threat triage
• Automated remediation
• Threat intelligence
• Behavioral and contextual analysis
• Messaging security across platforms such as Microsoft Teams and Slack
• Integration between human reporting and technical defenses
• Data loss prevention (DLP)

Where KnowBe4 Alternatives May Fall Short

The biggest differences among KnowBe4 alternatives emerge when comparing how far their protection extends beyond training and email.

• Hoxhunt, Infosec IQ and NINJIO: These security awareness training (SAT)-focused platforms may require separate products for native email threat detection, automated remediation, DLP and broader messaging security.
• Cofense and Proofpoint: While these vendors extend into phishing and email security, buyers should assess how closely their technical defenses connect with behavioral intelligence, training and protection across collaboration channels.
• Microsoft Defender for Office 365: Its connection to the Microsoft ecosystem may be limiting for organizations that need consistent visibility and protection across a set of different communication channels and technologies.

Achieving comparable coverage to KnowBe4 may require combining multiple products.

How KnowBe4 Approaches Collaboration Security

KnowBe4 connects employee reporting with AI-powered detection and response. PhishER Plus analyzes reported messages to prioritize threats and automate remediation, while threat intelligence helps security teams identify and respond to malicious activity.

Protection also extends to outbound communications. KnowBe4 uses behavioral and contextual analysis to identify sensitive information leaving the organization, helping prevent accidental data loss and intentional exfiltration.

These capabilities also feed information from real-world threats back into security operations and future employee defenses. This approach earned KnowBe4 recognition as a Leader in the 2025 Gartner® Magic Quadrant™ for Email Security Platforms and the 2026 Global Customer Value Leadership Recognition from Frost & Sullivan.

How KnowBe4 Alternatives Compare for Agent Security

AI agents can access sensitive data, applications and business workflows, creating risks such as prompt injection and data exposure that traditional security awareness platforms were not designed to address.

When comparing KnowBe4 alternatives for agent security, consider whether a solution can discover and govern AI agents, monitor their activity and protect against AI-specific threats.

What To Look for in Agent Security

Agentic AI security starts with visibility. Security teams need to identify which agents are operating, understand what data and tools they can access, and determine whether their activity creates risk.

Platforms should include:

• AI agent discovery and inventory
• Shadow AI visibility
• Agent governance
• Access and permission visibility
• Behavioral monitoring
• Risk assessment and prioritization
• Prompt injection protection
• AI-specific threat detection
• Visibility across human and agent risk

Where KnowBe4 Alternatives May Fall Short

Using AI in a security product is different from securing AI agents. While some KnowBe4 alternatives now extend into agent security, organizations should evaluate how comprehensively they address agent-specific threats and connect that protection with the rest of the workforce.

• Proofpoint: Buyers should assess the depth of capabilities across shadow AI detection, agent-to-agent trust validation, privilege escalation detection and identity mapping between humans and agents.
• Mimecast: Organizations should evaluate how its agentic AI security capabilities integrate agent discovery and governance with existing human-focused security protections.
• Microsoft: Its agent security capabilities sit within the broader Microsoft security ecosystem, making it important to consider how well they extend across applications and technologies outside that environment.

KnowBe4 brings agent security and human-focused security capabilities into the same platform, providing a connected approach to protecting the entire digital workforce.

How KnowBe4 Approaches Agent Security

KnowBe4 extends its digital workforce security platform to AI agents through Agent Risk Manager. The product discovers and inventories agents, including unauthorized shadow AI, giving security teams a centralized view of agents and tools across connected environments.

Agent Risk Manager monitors agent interactions for prompt injection, sensitive data exposure and excessive resource consumption. Centralized audit logs record agent actions for security and compliance teams.

Agent Risk Manager also accounts for how employees interact with AI agents. When a user prompts an agent to take a risky action, Agent Risk Manager can block the action and provide contextual coaching that explains the risk. That intervention can address the immediate action while helping employees understand safer AI use over time.

Why There Is No True One-to-One KnowBe4 Alternative

Alternatives may specialize in areas like phishing defense, security awareness, or email security, while KnowBe4 combines capabilities across attack simulation and training, collaboration security and agent security. That combination allows organizations to:

• Prepare employees to recognize and resist attacks
• Protect email, messaging and collaboration environments
• Discover, govern and protect AI agents
• Connect behavioral intelligence and risk visibility across the digital workforce

KnowBe4 brings these areas together within one platform rather than treating them as separate security initiatives.

What To Consider When Choosing a KnowBe4 Alternative

The right KnowBe4 alternative depends on your organization’s security maturity, existing technology stack, risk profile and required coverage. Before choosing a platform, evaluate five areas:

• Breadth of security coverage
• Behavioral intelligence and risk visibility
• Ability to address emerging threats
• Platform consolidation
• Measurable risk reduction

Breadth of Security Coverage

Start by defining what your organization needs to protect and whether SAT alone is enough. If your requirements also include collaboration and agent security, replacing one KnowBe4 capability may still leave other needs unaddressed.

Behavioral Intelligence and Risk Visibility

Look beyond training completion and phishing click rates when evaluating how a platform measures risk. Behavioral signals and individual risk insights can show which employees need additional coaching and where security teams should focus their attention.

Ability to Address Emerging Threats

Evaluate whether a platform addresses AI-assisted phishing, vishing, deepfakes, messaging attacks and agent-specific risks such as prompt injection.

Platform Consolidation

Consider how many products, consoles, integrations and datasets your security requirements demand. Specialized tools can offer valuable capabilities, but combining multiple point solutions can increase administrative work and fragment visibility across security controls.

Measurable Risk Reduction

A platform should show whether security outcomes improve over time, not simply document completed activities. Behavioral insights, risk scoring and longitudinal reporting can help security teams determine whether workforce risk is declining.
