![]() Antiviruses don’t help encrypt online traffic or bypass geo-restrictions the way VPNs do.VPNs, unlike antiviruses, don’t help detect and stop malware or malicious links.While VPNs help bypass geo-restrictions, firewalls don’t.A VPN, which prevents monitoring of a user’s traffic and secures data, doesn’t allow the user to establish restrictions (packet restrictions or network port restrictions) on the system in the way that a firewall does.Without being updated regularly to include the latest of viruses too in its database, an antivirus tool cannot work effectively to protect a system/network against threats and attacks. Antivirus tools are provided by third party providers and these software need to be updated they can, in fact, be set to update automatically. Based either on signature/code analysis or on behavior analysis, antiviruses identify, quarantine, analyze and remove all malware. In fact, though we often use the word antivirus, we’d be speaking about the antimalware software, which blocks not just viruses, but all kinds of malware- viruses, worms, trojans, spyware, adware etc. The antivirus software, which is the very basic security software for any computing device, works by detecting, identifying and removing malicious software. Still, firewall security is a must, for any computer system. Thus, malicious files, programs or websites that are not included to be blocked wouldn’t be blocked and hence a firewall alone won’t work to secure a system. He should also remember that a firewall allows or restricts programs, services etc based on predetermined rules and hence it doesn’t have the capability to determine, by itself, what is malicious and what not. In fact, most OSs (operating systems) come with pre-installed firewall if the user wants, he can configure the firewall to suit his needs. This is done by inspecting and blocking (or allowing) packets based on a certain set of predetermined rules. ![]() A firewall could be a hardware device or a software device and helps block malicious programs, restrict access to unsecured websites etc. The firewall, which is a must for any computing device, secures the system by monitoring and filtering incoming and outgoing traffic. It also helps the user bypass geo-restrictions thus, a user can browse websites/services that are restricted in his country or area if he uses a VPN. The VPN, which works even when a user is on public Wi-Fi, masks the IP address, thereby giving the user some online anonymity. This is done by encrypting users’ online traffic and thus protecting sensitive data and the entire communication from being seen by hackers or even surveillance agencies. VPN, or Virtual Private Network, helps users protect their privacy when they are online. To understand this better, it’s necessary to know in detail how these different software function and what their uses are. ![]() Well, the answer is- use them all since they work best in unison. ![]() People often get confused with difference between VPN, firewall and antiviruses they seem to be always wondering which of these security solutions they should use to ensure maximum security. ![]()
