How secure is a VPN? Understanding VPNs And Cyber Security

With so much talk about VPNs nowadays, you’ve probably heard that there are valid security reasons to get one. To protect your Internet usage, and your network and computer hardware, a VPN is one of the best tools you can employ. You can get many of them for free, though they take your data too, so the best ones are paid if you want full, uncompromising protection.

Here we have explained exactly how VPNs are a fast, inexpensive way to bolster your cybersecurity. You don’t need to have a degree in computer science to work with one – there are many great services out there that protect your data, mask your activity, and fend off ISP tracking attempts.

Encryption Protocols

While VPNs can hide your IP address and physical location, they also employ sophisticated encryption techniques that protect you and your online activities. One of the industry leaders in VPN encryption is Surfshark, which uses very advanced AES-256-GCM encryption to protect those who use its service.

The field of Cybersecurity, and its threats, change constantly. That’s why it’s important to choose a suitable provider that regularly updates and improves its services to stay ahead of the curve.

The 256 in AES-256-GCM means that it’s 256-key encryption using AES-GCM protocol. This is more sophisticated than other protocol types that are currently out there, among other security benefits that keep hackers smarter and more unscrupulous than us at bay.

Additional Security Protocols

Many VPN providers, Surfshark included, offer several security protocols that you can use as part of your VPN plan. These combine with other VPN functions to provide more customized protection for your online activity.

Following the example of Surfshark, three very useful security protocols are available that keep you safe from cybersecurity threats:

  1. IKEv2: Meaning Internet Key Exchange version 2, this is a protocol that kicks in during close-range connections, mainly with mobile users. If you use a mobile device for work or to handle other sensitive data and communications, protecting it with IKEv2 is essential.
  1. OpenVPN: OpenVPN is a security protocol available for Windows, iOS, Android, Linux, and even Fire TV. It’s an open-source protocol that works well for long-distance connections. As a result, it’s updated constantly. By an army of ethical hackers and developers who want to see the service improved to protect more people like you.
  1. ShadowSocks: VPNs aren’t legal everywhere, especially in countries that have historically tried to stop their citizens from accessing free-flowing information online. However, there are security protocols that help users in those countries from reaping the benefits of VPNs, and ShadowSocks is one of them.

There are many other security protocols you can apply to your VPNs. So you should definitely shop around and find one that matches you and your online activities. Fortunately, paid VPN services offer you many security protocols to choose from.

Browsing Protection

While security protocols protect your online activities from the backend, many VPN functions protect you from human error when browsing. Has a pop-up ever ambushed you? So you accidentally click on it? When that happens, you may be placing your data at risk.

Features like Cleanweb protect your browsing by stopping pop-ups and other malicious practices that less-than-reputable websites use. It doesn’t just protect your computer from the Internet, it protects you from yourself, as you can’t click on spoofed permission buttons or pop-ups.

Oftentimes, you won’t even know if you clicked on a bad link or pop-up, but Cleanweb makes things safer. The best way it does this is by simply restricting the sites that have malware and other red flags on them. The same for suspicious links. In both cases, you can often customize your VPN profile to let sources you trust through the protections.

Problematic sites are tracked by a database that VPN providers keep. And regularly update/correct. Currently, there are over a million sites registered!


That’s how VPNs can help improve your cybersecurity. With a combination of sophisticated encryption and security protocols, with front-end browsing protection. VPNs can make your online activities much safer.

In conclusion, they are a great addition to anybody’s security profile. They are especially important – and sometimes mandated by companies or governments. If you work somewhere that handles and exchanges sensitive data. If those places get hacked. Moreover, they’ll do it by compromising the one employee that didn’t protect themselves. Lastly, if you work with sensitive data, your work provider may even provide complimentary VPN services for you!
