Last year in 2024, I started an online store. Everything was running well until one day, my site crashed. Customers complained that they could not access their accounts or track any details. I was shocked to learn that hackers had taken advantage of a security weakness. I did not even know my website had vulnerabilities but after some time, I learned about free vulnerability scanners. These tools detect security risks before hackers can use them.
I started scanning my site regularly and I have not faced any attacks since then. If I had known earlier, I could have saved time, money, and stress. Now, I tell everyone to use these free tools. Many businesses now use vulnerability scanners to stay safe without spending money. If you want to protect your data without spending money, here’s a list of the best free vulnerability scanners you can start using today.
What Is a Vulnerability Scanner?
A Vulnerability Scanner is a tool that checks your system, network, or website for security weaknesses. It scans for outdated software, open ports, and weak passwords that hackers can use to gain access. Vulnerability Scanners are essential in identifying potential security threats and ensuring robust protection of the enterprise IT infrastructure. By identifying vulnerabilities early, you can fix them before hackers take advantage of them.
