Is it safe to use a VPN?


VPNs are not inherently secure, so you might be wondering if VPNs actually work. We explain that virtual private networks are simply used to allow remote access to private networks. VPNs have been used by businesses for many years to enable employees to remotely access company resources.

A username and password are all that are required for small applications like this. With their username, the employee connects to the company VPN and has access to the entire internal network. It’s a virtual private network that is protected by login credentials.

Absolute secrecy

Perfect forward secrecy is (PFS), a crucial, but rarely discussed topic in VPN security. Although AES is as secure as Fort Knox it does not make it impenetrable. Ethan Hunt was able to destroy a heavily guarded CIA facility in Mission Impossible. He didn’t use brute force tactics. The same principle applies to encryption, no matter how extravagant it might seem.

Trustwave, a cybersecurity research organization, was able to crack AES in 2013. After the death, it was revealed that the key reuse was the biggest vulnerability. Here lies the secret of the keys.

Perfect forward secrecy means that every session is considered “new” within the encryption realm. The server keeps the encryption keys that encrypt or decrypt traffic when you connect to the VPN server. These keys can be re-used by anyone who can see the encrypted connection and wait for them to crack one key.

This flaw is not unlike the minor security holes in Mission Impossible’s CIA base. The perfect forwarding secret ensures that no traffic from previous sessions can be compromised. Numerous services, such as ExpressVPN or private Internet access, use PFS to provide core security elements.


It is important to choose the protocol used to establish this connection. Point-to-point tunnelling protocol is a popular and early option in the above scenario. It does not offer any additional encryption. It’s fast, but not secure and has many known vulnerabilities.

If you use PPTP with a VPN your connection may not be very secure. This is usually not an issue. PPTP is still supported by a few VPNs, but most of them have gotten rid of it.

OpenVPN is currently the preferred protocol for ISPs. OpenVPN still allows remote connections to a network server, but it also adds additional encryption. Although the extra encryption slows down your connection, it is also more secure.

The protocol determines your VPN security. OpenVPN and AES are the best VPN services. Although key sizes can be varied, this does not affect the security of AES. There are currently no known AES exploits, provided that the key size is correctly implemented.

The quality of encryption is improving every day. WireGuard is being used by many VPN providers. It is faster than OpenVPN and more secure. It uses the ChaCha20 cryptographic key, which has no known exploits at this time.

You don’t need to worry about VPN security as long as you use a combination of these protocols or cyphers. As long as everything is properly implemented by the VPN provider

Experts recommend thinking twice before you choose a virtual private network (VPN) service that is free from Google Play or the App Store.

An encrypted tunnel is created when you connect to a VPN. This gives the user an additional IP address, possibly in another country, and protects Internet traffic from being decrypted by local network administrators or Internet service providers.

What’s the danger?

In an interview with Wired, Simon Migliano from’s head of research explains how free VPNs can lead to data leakage as well as active surveillance.

Commercial VPN providers, such as TunnelBear, Windscribe and ProtonVPN, offer free layers of security that can be used to promote services or public goods. There are also advertising-funded services for mobile devices, so you need to be cautious when using them.

Comparitech researchers discovered that UFO VPN, a Hong Kong provider, had stored this user data, as well as access records and plaintext passwords, in a public database. (Comparitech representatives previously stated that they did not keep logs of user activity).

Comparitech representatives stated that free VPN services are not recommended as they have weaker privacy and security policies. Many providers gather user data and use it to market. This is a fundamentally bad thing for VPN privacy.

Although it is rare for such out-of-contract storage or mishandling to be disclosed, many free mobile VPNs have poor data policies or none at all. These are only a few of the issues identified during the analysis.

VPNs that are free do not guarantee privacy.

They can leak information about users’ online activities if they are not correctly configured. Comparitech’s top 150 VPN services for Android were tested last year by 25% of its exports. The privacy of nearly every tenth user was compromised.

Hola VPN was also problematic with over 50 million Android installations. Experts say that finding a VPN that doesn’t track your browsing activity is difficult due to the high turnover of such apps.

What does a VPN do to the law?

It is important to know where your VPN is located. Local laws govern what data law enforcement agencies and governments can access. Top10VPN featured several VPN providers that offer privacy and security logs, based in China and Hong Kong. Security experts are concerned by the recent Hong Kong security law changes that require service providers to retain user activity logs.

Many privacy-focused VPN companies have legal headquarters in Panama and the British Virgin Islands because of data retention laws in Hong Kong and Russia. These territories do not fall under international intelligence-sharing and government oversight.

Wired reports that data retention laws in certain countries, such as the UK, have resulted in logs of user activity being shared openly with law enforcement agencies. This is a problem even for law-abiding VPN users.

How can you protect yourself?

You should never use a VPN to protect your privacy. You are choosing another company to monitor your activities, not your provider. Even if you only need a VPN for a region switch, you should first consider what data your phone and activity information are being shared with and to whom.

Although a properly configured VPN endpoint is the best way to protect privacy, it is not possible. Wired experts confirm that there are commercial, non-exploitative VPN service providers. You can even find free ones.

It is important to remember that you can only request VPN services if your provider agrees with you. You can check their policies regarding transparency and logging to see if there have been any lawsuits or security problems in the past.

Is private browsing and VPNs really secure?

You probably know that the internet can present all kinds of risks to your business and organization, regardless of whether you work for yourself or for a company.

Connecting to the internet exposes you and your business to thieves and hackers who can steal everything from personal information, browsing history, and payment data.

You may have considered private browsing or a VPN to protect your business online. Which one is best for you?

What is private browsing? How can I use it?

Private browsing is an option that many web browsers have. These features are accessible in most major web browsers and can be accessed via the File menu. Take this example:

  • Google Chrome offers an incognito mode
  • Microsoft Edge offers an InPrivate browsing option
  • Safari allows private browsing
  • Firefox allows private browsing
  • Opera comes with private tabs.

In simple terms, private browsing is a method of browsing in which the browser does not save browser history, search history or local data such as cookies.

Private browsing is really private?

Private browsing will block your browser from saving information on your computer or device, but it won’t necessarily stop communication between your computer (and your Internet Service Provider) (ISP).

Third parties can also track private browsing activity, which can then be used to hack into the operating system logins.

What is the safety of private browsing?

Private browsing is a popular way to protect yourself from malware, viruses, and hacking attempts. Because local data is not saved, this will protect you from viruses and other malware. It will therefore protect them against fraud and theft, such as when they enter financial details or passwords. Unfortunately, this is false.

Private browsing is dependent on your Internet Protocol (IP), which your Internet Service Provider provides. Third parties can still see your browsing session and exploit it. In the past, browser extensions, HTML5 APIs and bugs have all been sources of accidental leakage. They have enabled third parties to access Internet history and search results through private browsing.

A VPN is the only way to protect your web browsing, search and history data.

What is a VPN?

VPN stands for Virtual Private Network. Virtual private networks protect your internet traffic and identity online, making it more difficult for hackers to steal your data.

What can a VPN hide from your history?

Your Internet Service Provider (ISP), provides your Internet connection. Your IP address is used to monitor your internet activity. Your web traffic is routed through the servers of your ISP. They can log everything you do online.

Although your ISP may appear trustworthy, they can still share your browsing history with advertisers and the police, as well as other third parties. Hacking is possible through your Internet service provider. If it is compromised, your private and personal data could be exposed.

This is particularly important if you frequently connect to public Wi-Fi networks. It is possible for someone to monitor your Internet traffic and steal passwords, personal information, and even your entire identity.

Is a VPN really so secure?

Virtual private networks are not the same as anti-virus software. They can only protect your IP address and encrypt your Internet history. They will not protect you if your computer is compromised by phishing sites, or if you download corrupt files.

You are still at risk if you use a VPN.

  • Trojans
  • Bots
  • Malware
  • Spyware
  • Viruses

No matter if you use a VPN, any of these viruses can infect your computer. To ensure maximum security, a VPN should be used in conjunction with anti-virus software.

Selecting a reliable VPN provider

Your ISP won’t be able to see your Internet traffic but your VPN provider will. If your VPN provider is compromised, it will also be compromised. It is important that you choose a VPN provider that you trust. Before you buy, we recommend that you look around and read unbiased reviews.

VPN protects your privacy

What does a VPN do to protect your privacy?

VPNs protect your data against hackers by using encryption protocols. VPNs make your connection anonymous by hiding your location and personal data.

Each VPN protocol determines how an application and server connect to one another, and the methods used to transmit and encrypt data. VPNs can use a variety of methods to protect your data flow through an encrypted tunnel.

OpenVPN is the most secure protocol available, and it’s offered by many providers. OpenVPN is, as the name suggests, open-source software. This means anyone can verify that the code works properly. Although it was originally designed in 2001, much has changed in technology over the past twenty years.

WireGuard, a relative newcomer in the world of VPN protocols is now available by many providers including Surfshark, Private Internet Access and NordVPN. It serves as the basis for NordLynx, NordVPN’s own protocol. Our testing has shown that it can connect up to three times faster than OpenVPN.

Another effective way to protect your online privacy is to offer a no-logging policy. Your personal data will not be stored by the VPN provider.

Logging is not an option. However, it should only be used to log basic information such as the number and type of users who connect to the same server. Be aware that a policy that logs your activities can be more intrusive than a policy that only stores basic data. This data includes browsing history, DNS queries and URLs visited. It also contains usage metadata. These are things you don’t want to be exposed to the public if they were stolen.

Anonymous payments, such as PayPal or Bitcoin, ensure the security of your online banking information. Some services don’t even require your email address for registration. Mullvad allows you to create an online account without revealing any personal information.

Another feature that improves VPN security is shared IP addresses. This trick makes it nearly impossible to track down you because multiple users can be assigned the same IP address from different locations.

Is the VPN service able to access your data?

A non-logging VPN is the best option to protect your data from being passed to third parties. Your digital footprint will still be protected even if authorities demand access to your ISP (e.g., in criminal investigations). This is because companies cannot share information that is not there.

A paid service will generally offer better protection for your online activities, but not all have sufficient no-registration policies. Free VPNs may use your data to market their products. This is not the way you want to stay safe online.

Keep in mind, however, that not all digital footprints can be protected by the best services. Logging into an online account, or social network can allow you to be tracked up to a certain degree. Some apps, for example, store information about your location.

Conclusion about security and a reliable VPN

VPN security isn’t a binary topic. There are many variables that can affect your internet security. Services like ExpressVPN, CyberGhost and NordVPN meet all requirements, making your Internet connection more secure.

A VPN is highly recommended. Make sure you choose one that is able to protect you. We would love to know what service you use. Please leave a comment below.
