When it comes to your business security, what’s the first thing that comes to mind? Most likely the trusty old firewall. In the event of a successful cyberattack, most victimized organisations will raise the question: “Why wasn’t our firewall able to protect us?”

Even though firewalls are an essential component of cybersecurity, alone they can’t stop the flame from rising. Read on to understand why you need a total and comprehensive cybersecurity strategy and solution.

What are the limitations of a firewall?

Unfortunately, security threats are constantly evolving and are designed to circumvent common and basic security tools, such as firewalls. As a result of The Internet of Things (IoT) and increase in remote working as a result of the digital age and the most recent COVID-19 pandemic, nearly any smart device from phones, laptops, printers, tablets and televisions can be connected to the business network – creating an access point for cybercriminals.

Your firewall is pretty good at protecting your office network. After all, that’s what it was designed to do. But, what happens when an employee accesses their email or files from their phone? What about when they connect to the WiFi at a restaurant? Your network security is only as strong as its weakest link. You could have the strongest, most expensive security system on your laptop, but it won’t do you any good if an attacker sets up a fake WiFi hotspot and intercepts all the data.

Firewalls are primarily used to prevent attacks originating from outside the system. What if a threat makes it past the firewall or originates from the network itself?

Firewalls are also extremely limited in their capacity to prevent phishing, scams, ransomware and much more in addition to just typical malware. Some of these rely on tricking a user into taking a desired action like surrendering confidential information or disabling a firewall or antivirus. Unfortunately firewalls can’t stop human errors or fix poor administrative practices and security policies. Firewalls need to be consistently updated. New threats arise every day and if firewalls aren’t updated they may not protect you from the latest threat.

Traditional network security, like firewalls doesn’t extend to the mobile-first, multi-device reality that we live in today. Massive hikes in web traffic, constantly evolving threats and other dangers are not easily detected. Firewalls are a reactive method as you can only protect devices after threats have been detected.

Total cybersecurity for effective defense

Now that multi-devices and IoT are complicating secure networks with added vulnerability, increased endpoint security is a must-have for optimal protection. Total cybersecurity extends to analyse potential cyber threats to an organisation. Threat intelligence assists organisations evaluate the risks associated with rare and common risks. Security needs to be as modernized and sophisticated as potential threats. Real time protection and predictive analytics need to be in place to identify malicious behaviour and respond to emerging threats. A total cybersecurity system needs to proactively detect and neutralize advanced threats that typically evade security systems. Organisations need a first line of defense to threats you can’t see or immediately repel with a firewall. A successful cybersecurity approach has multiple layers of protection across computers, networks, programs and data and accelerates key security operations which are prevention, detection, investigation and remediation.
