The idea of a firewall might sound old-school—like something from the early days of antivirus CDs and dial-up internet. But strangely enough, in 2025 firewalls are more important than at any point in the past decade.
Why?
Because modern cyber threats aren’t just about malware anymore. They involve credential theft, API abuse, bot-driven attacks, and network exploitation. And a badly configured firewall is like leaving your shop lights on and the shutters half-open at night.
Companies that treat firewalls as “set it once and forget it” devices are the ones that end up in trouble.
Why Firewalls Still Matter (A Lot)
A firewall is the only thing standing between your internal systems and millions of automated scans happening every day.
Security researchers found that Indian IP ranges experience the highest volume of malicious probing attempts in Asia. This is why having a firewall service in India that’s actively managed and regularly updated is now essential—not optional.
A striking example appeared in The Economic Times when they covered a breach at an SME in Surat, where attackers entered through an outdated firewall rule that had been left open for years.
The attackers didn’t break encryption or crack passwords.
They simply walked through a forgotten open port.
What Is Firewall Management and Why Is It Required?
Firewall management isn’t just installing the device. It involves:
- Reviewing firewall rules regularly
- Removing unnecessary access
- Updating firmware
- Watching real-time traffic
- Identifying unusual patterns
- Blocking known malicious IP ranges
- Ensuring compliance with security frameworks
Most breaches involving firewalls happen because of human oversight—not technical complexity.
How Often Should Firewall Rules Be Updated?
At least once a month for growing companies.
Once a week for high-risk sectors like finance or healthcare.
But realistically, the rule updates should be based on changes in your business—not a calendar:
- New vendors
- New applications
- Additional remote employees
- Cloud migrations
- New branches
Every change in your environment should trigger a firewall review.
This is why firewall management services have become popular. Most businesses don’t have the time or expertise to constantly tweak firewall policies.
Can Firewall Services Protect Remote Employees?
Yes—if configured correctly.
With remote and hybrid work becoming permanent, firewalls now extend beyond office walls.
TechRadar Pro covered how misconfigured home networks were responsible for a spike in backend intrusions during the pandemic.
Modern firewalls support:
- Secure VPNs
- Zero-trust access
- Identity-based rules
- Cloud traffic inspection
This ensures remote workers connect through secure tunnels instead of exposing your company’s entire network to home Wi-Fi vulnerabilities.
FAQs
- What is firewall management and why is it required?
It’s the ongoing process of updating firewall rules, monitoring traffic, closing unused access points, and ensuring security policies stay relevant as the organisation evolves.
- How often should a company update firewall rules?
Monthly at minimum; more frequently for high-risk industries or rapidly evolving environments.
- Can firewall services protect remote employees?
Yes. With VPNs, identity-based rules, and zero-trust configurations, modern firewalls secure remote access effectively.
