With so many security tools out there, it’s difficult to determine the differences between certain types of products. One question you be asking yourself: Is firewall and antivirus the same thing? Show
Antivirus and firewall are sometimes used interchangeably, but each tool works differently to secure an environment. It’s especially important to know those differences when making a purchasing decision. We’ll go over how each product works, and then discuss differences between the two. What Is Antivirus Software And How Does It Work?Over the years, antivirus (AV) software has evolved to also protect against malware. It continuously scans and analyzes data against a library of known malware types. Antivirus generally uses three different detection techniques:
What Is a Firewall And How Does It Work?A firewall allows or denies incoming and outgoing traffic from reaching its destination depending on configured rules. Since firewalls are often the first line of a network’s defense, they are considered a form of perimeter security. Firewalls act as a filtration system, blocking malicious traffic such as viruses, malware. Firewalls use at least one of the following techniques to monitor network traffic:
Differences Between Firewall and AntivirusThere are a few differences between firewalls and antivirus. One of the major differences is that firewalls can be hardware or software, while antivirus is always a software product. Also, the two detect malicious behavior differently; antivirus scans data and determines whether it is a virus, while a firewall filters data depending on policies. We’ve highlighted the major differences between firewalls and antivirus products in the chart below:
However, the differences between antivirus and firewalls are blurring as vendors develop new products such as next-generation firewalls (NGFW) and next-generation antivirus (NGAV). These two categories of products address the limitations of their more traditional predecessors. Next-generation firewalls (NGFW). These advanced firewalls combine traditional network firewall technology with web application firewalls (WAFs) to protect against both web-based and network attacks. A NGFW also incorporates other capabilities, such as intrusion prevention systems (IPS), antivirus and encrypted traffic inspection. One defining feature of a NGFW is deep packet inspection, which inspects the data within the payload of the packet rather than just the packet header. Next-generation antivirus (NGAV). Next-generation antivirus takes a cloud-based approach for easier deployment, and uses AI and machine learning rather than signature-based detection to detect malware that traditional antivirus wouldn’t catch, like fileless malware and new malware families without signatures. NGAV is sometimes used interchangeably with endpoint protection, although the latter usually refers to a more comprehensive feature set. Choosing Between Firewall and AntivirusFirewalls and antivirus both have their limitations, so choosing one tool over the other would result in gaps across your security coverage. Antivirus and firewall tools work together to secure an environment; if a virus bypasses the firewall by entering the environment through a download, for example, antivirus software can scan and block that virus. Strong security programs take a layered approach, protecting your environment at each level — from the system to the network to the application level and beyond. Both antivirus and firewall products are important for any security stack, but there’s no single product that will fully secure an environment against cyberattacks, especially against ransomware. The best way for organizations to protect themselves is with a layered, nuanced approach to security. Investing in a next-generation firewall (NGFW), a robust antivirus product, and endpoint detection and response (EDR) are important steps. Not all antivirus and EDR solutions are created equal, either, so it’s important to test these products before you purchase to ensure that they detect attacker behaviors like process activity, network connections and registry content. But those tools are less effective without a way to receive alerts and have visibility into an environment, which is why it’s crucial to have a centralized logging solution like Blumira.

What is difference between antivirus and antivirus software?While both anti malware and antivirus are utility programs designed to protect your system from all kinds of malicious software, antivirus software is designed specifically to protect your digital environment against more established threats, such as viruses, worms, and Trojans.
What is antivirus and firewalls characteristics of good firewalls?A firewall deals with external threats from unauthorized users while anti-virus protects threats from within and camouflaged files sent from outside in various forms. A firewall works by monitoring and filtering while anti-virus works by detecting a virus in infected files and deleting them.
