Empowering Organizations Through Free Cybersecurity Awareness Training
At Computer Security US, our mission is simple: make cybersecurity awareness training available to everyone, educate workforces on phishing and social engineering threats, and reduce the risk of breach attacks across organizations of all sizes.
Phishing remains the leading cause of data breaches worldwide — and the most effective defense is a workforce that knows how to recognize and respond to attacks before they cause damage. That's why we built two complementary platforms: a free cybersecurity awareness training program for individuals, and a phishing simulation platform that lets organizations test and reinforce that knowledge with real-world attack scenarios.
Whether you're an individual looking to sharpen your security instincts or an organization seeking to reduce human risk across your workforce, we have the tools to help you build a security-conscious culture — starting today.
Our free cybersecurity awareness training covers five essential modules: Understanding Cybersecurity Threats, Password Security & Authentication, Phishing & Social Engineering, Data Protection & Privacy, and Incident Response & Reporting.
Upon completion of our free cybersecurity awareness training, participants can receive an official verifiable certificate by making a small donation (starting at $1) to support the program. Your donation helps keep training free for everyone.
Complete the training at your own pace. Each module includes video instruction, detailed content, and knowledge checks to ensure understanding before moving forward.
All 5 training modules are completely free with no hidden costs, subscriptions, or paywalls. A small donation is only required if you'd like to receive your official certificate.
Cybersecurity threats evolve constantly. Our training materials are regularly updated to reflect the latest threats, techniques, and best practices in the industry.
Access our free cybersecurity awareness training from any device, anywhere. All you need is an internet connection to begin your cybersecurity education journey.
Need to test your workforce? Our Phishing Awareness Training platform at phishing.computersecurity.us simulates real phishing, vishing, and smishing attacks so employees experience threats firsthand — not just read about them.

Computer Security US is owned and operated by Cleared Systems, LLC, a company dedicated to advancing cybersecurity education and awareness across organizations of all sizes.
Cleared Systems, LLC understands that cybersecurity is not just a technical challenge—it's a human one. That's why we've invested in creating this comprehensive free cybersecurity awareness training program that focuses on empowering individuals with the knowledge they need to become the first line of defense against cyber threats.
Our commitment to providing free, high-quality security education stems from the belief that a more secure digital world benefits everyone. By removing financial barriers to cybersecurity training, we help create a safer online environment for businesses, organizations, and individuals alike.
Phishing is a type of cyberattack in which criminals impersonate a trusted person, organization, or brand to trick individuals into revealing sensitive information — such as passwords, financial details, or login credentials. Phishing attacks are the most common entry point for data breaches, ransomware, and account takeovers affecting organizations of all sizes.
While the term "phishing" originally referred to fraudulent emails, modern attacks take many forms:
Deceptive emails that appear to come from a trusted source, often containing malicious links or attachments. Attackers frequently use lookalike domains and homoglyph characters to make emails appear legitimate.
Voice-based phishing conducted over the phone. Attackers impersonate IT support, bank representatives, or government officials to extract sensitive information verbally.
Phishing delivered via SMS text message. Attackers send urgent-sounding texts with malicious links, often impersonating delivery services, banks, or employers.
Understanding what phishing is and how to recognize it is one of the most important skills any employee or organization can develop. Our free training covers phishing recognition in depth — and our simulation platform lets you put that knowledge to the test with real-world attack scenarios.
For organizations that need to go beyond individual awareness training, we offer Phishing Awareness Training — a paid SaaS platform purpose-built for simulating real-world phishing, vishing, and smishing attacks across your entire workforce.
The platform automatically generates realistic lookalike domains, misspellings, and homoglyph variations of your organization's domain — mirroring exactly how attackers craft convincing campaigns. Training interfaces are animated to mimic real devices including Outlook, iPhone Messages, and Android Messages, so employees experience simulations that look and feel like genuine attacks.
While our free cybersecurity awareness training will always remain free for all users, maintaining and improving this platform requires resources. We rely on the support of our community to continue providing this valuable service.
Note: All 5 training modules are completely free and accessible to everyone. A small donation (starting at $1) is required only to receive your official certificate. Your donation directly supports keeping the training free for others.
