Why is it critical to know and implement the best firewalls for small businesses? Well, cybercrime in information technology development has reached new heights, and according to Cybersecurity Ventures, the damage it causes to the online landscape is forecasted to grow to $10.5 trillion annually by 2025. Phishing, malware, account takeover, credential abuse, ransomware, cryptojacking, and zillions of other severe cyber security attacks are commonplace these days. Since the amount of threats is constantly increasing, the cost of a data breach has earned a king's ransom. Small businesses are especially vulnerable to cyber attacks as they often lack high-end training and security resources to defend against cybercrimes. For this reason, using reliable firewalls is crucial for keeping customer and company data safe and secure. This article will help you learn the nuts and bolts of firewalls. You will also get a clear overview of the best firewalls for small businesses to pick the most suitable option to safeguard your network. InvGate Insight ITAM software 4.4 Gartner ★ ★ ★ ★ ★ Cyberattacks put a company's reputation, assets, data, and information technology equipment at risk, and, what's more, they also affect other connected enterprises that are part of the supply chain, causing a domino effect. Hacking a business network results in severe damage to data and systems, as cybercriminals can easily access company banking information, client credit card details, company intellectual property, etc. Consequently, small businesses often shut down after experiencing financial losses, spending time and resources on eliminating cyber threats and adjusting the network, and losing customer trust due to compromising sensitive data. That is why protecting your business against cybercrimes should be a top priority. To address the elephant in the room, double-check the third parties you work with, opt for robust antivirus software, secure your business Wi-Fi network, and limit the number of people who have access to the company's critical data. In addition, you can also familiarize your employees with cyber security, black-hat activities that can cause severe damage to your systems, and come up with an action plan to keep company data safe. In line with this, your employees should maintain password hygiene, recognize fishy emails or attachments, avoid malicious software downloads, etc. What's more, make sure your staff exercises caution during web surfing sessions and utilizes only trusted and secure websites for browsing. To help your employees be confident about sites they leave their personal data or company information on, encourage running a full website audit highlighting the most critical site security issues related to secure encryption protocol for user data protection. And most importantly, look through the best firewalls for small businesses to deploy a potent firewall software for your company. Such a tool aims to proactively defend your network and block unauthorized traffic that can potentially cause damage. Simply put, firewalls allow you to prevent hacker attacks and save your business from the above deplorable scenarios. There are five primary types of firewall software: packet filtering, stateful inspection, circuit-level gateway, next-generation, and proxy service firewalls. Packet-filtering firewalls or stateless inspection firewalls are static firewall software performing basic filtering at the network layer by analyzing individual data packets sent across the network according to their destination and source. Stateful inspection firewalls function at the transport level and allow establishing of diligent rules that match particular conditions. They can track and memorize the ongoing and previous connections and therefore don't need the re-approval for each data packet. Another type of firewall software is the circuit-level gateway firewall. It performs at the session level and concentrates on defending user datagram protocols (UDPs) and transmission control protocols (TCPs). Such firewalls help to track handshaking between data packets from trusted servers, clients, and untrusted hosts. Next-generation firewalls are threat-specific, multilayer firewalls combining the features of other common firewalls with additional security devices and software. Such robust functionality allows NGFWs to inspect and determine advanced malware and other complex threats in detail to conduct data analysis on a granular level. Proxy firewalls, also called application-layer gateway firewalls, filter packets and read application protocols, providing advanced protection at the application layer. Proxy firewall security software provides complete control over network traffic. Small businesses have unique pricing, setup, features, and installation requests when seeking dedicated firewall software. Below you can find the top ten best firewalls for small businesses to help you decide on a trustworthy solution for enhanced cyber security.Why are firewalls important for small businesses?
