An outdated firewall can leave your business exposed to modern cyber threats. Here are five red flags to look out for. 

1. Slower Network Speeds
If your internet feels sluggish, your old firewall might be struggling to keep up with today’s traffic demands.In today’s day and age, businesses are handling more traffic than ever which are inclusive of cloud apps, video conferencing, file sharing, and IoT devices which all push huge volumes of data across various networks.

2. Increased Cyber Incidents
Are you noticing more spam, phishing attempts, or malware alerts? It’s a sign your firewall isn’t blocking enough. Here is a familiar example: imagine one of your staff receives an email that looks like it’s from your bank, asking them to “verify” account details. The logo looks real, the wording feels extremely urgent, and before they know it, they’ve clicked a malicious link. Without a proper firewall filtering inbound traffic, that email slips through your network, potentially exposing your entire business to fraud or ransomware.

3. No Remote Worker Protection
In 2025, remote work is the norm. If your firewall doesn’t protect employees working outside the office, it’s outdated.For example, an employee logging in from a coffee shop’s WiFi could expose your business data to hackers on the same network.

4. Lack of Regular Updates
Modern threats evolve daily. If your firewall provider isn’t pushing frequent updates, your defences are already behind.

For example: In June 2024, the South African National Health Laboratory Service (NHLS) was hit by a ransomware attack that compromised its systems and infrastructure. The attack was claimed by the BlackSuit ransomware group, and the NHLS has stated it will not communicate with its assailants and won’t pay a ransom**

Another example, dating back to earlier this year is that South African Airways experienced a cyberattack that temporarily disrupted its website, mobile app, and internal systems. The airline swiftly restored services by activating its disaster recovery protocols. **

5. No Visibility or Reporting
Business leaders need insights into what’s happening on their networks. If your firewall doesn’t provide reporting, you’re operating blind and here’s another example why, imagine a small marketing firm notices unusual network slowdowns. Without firewall reports showing blocked threats or attempted intrusions, the IT team can’t identify the source causing downtime that could have been prevented with proper monitoring and reporting.

How can our team at Summit Networks solve this? 

Our firewall solutions are scalable, secure, and constantly updated to match new threats. We also provide regular monitoring and reporting, so you always know your business is safe, wherever you are. 

If you spotted one or more of these signs, it’s time to upgrade. Don’t wait for a cyber-attack to force your hand.

What is a Firewall?

Think of a firewall as the security guard at the entrance to your office. It monitors all traffic coming in and out of your network and blocks anything suspicious. Whether it’s a hacker trying to gain access, or malware hidden in an email, a firewall acts as the first line of defence. It is what basically defends your staff and company against all those scam emails that are created to get all sorts of information that can be used against your organisation. 

Why Firewalls Matter in 2025

• Rise in Cybercrime: South Africa has the third-highest number of cybercrime victims globally. To give you an idea of how bad it is, In 2022 South Africa rose from 6th to 5th position globally. Each year, this number keeps decreasing, which in this case, is NOT good. **
• Remote & Hybrid Work: Employees connecting from home need extra layers of protection, especially since the pandemic started. With a lot more organisations facilitating hybrid work, cyber criminals have found a gap.
• Regulatory Compliance: The POPIA act actually demands that businesses protect sensitive consumer data.

In 2025, the line between home and work has never been blurrier. With remote work, online learning, and shared digital devices now a part of everyday life, South African families are more connected than ever… And so are the risks.

While your child might be watching YouTube, downloading games, or chatting on social media, one innocent click could expose your personal data, your home Wi-Fi, or even your company’s network to cybercriminals.

Why Parents Need to Think Like Cybersecurity Managers

Let’s face it: children aren’t thinking about malware, phishing emails, or secure passwords. But the apps and platforms they use can become the back door cyber attackers exploit.

Especially in households where parents work remotely, that back door doesn’t just lead into the home, it leads into your company’s systems.

At Summit Networks, we believe that cybersecurity starts at home. So we’ve created a simple, practical checklist for South African parents to help keep both family and business safe.

Parents’ Cyber Safety Checklist

1. Secure Your Home Wi-Fi

• Use a strong password (not the default one).
  
• Rename your network (SSID) to something generic.
  
• Disable remote access to your router unless absolutely necessary.
  

2. Install Antivirus & Firewalls

• Use trusted antivirus software across all devices.
  
• Enable built-in firewalls on routers and devices to block threats.
  

3. Educate Your Children

• Teach them about stranger danger online.
  
• Show them how to recognise suspicious links, pop-ups, or download prompts.
  
• Encourage them to ask you before installing new apps or clicking unknown links.
  

4. Create User Profiles

• Set up separate user accounts for children with limited access.
  
• Use parental control tools to block inappropriate or risky content.
  

5. Use Strong Passwords & 2FA

• Teach your kids how to create secure passwords.
  
• Enable two-factor authentication (2FA) on accounts wherever possible, especially for devices used for both work and play.
  

6. Regular Device Updates

• Keep all software, apps, and operating systems up to date to patch vulnerabilities.
  
• Enable automatic updates where possible.
  

7. Monitor & Review

• Check browser histories, app permissions, and downloaded content regularly.
  
• Use software that alerts you to risky or unusual behaviour on shared devices.
  

Why This Matters for Businesses Too

If your home devices are compromised, your employer’s network could be next. Whether it’s through file sharing, VPN access, or synced cloud apps, cyber risks don’t stop at the office door anymore.

Summit Networks works with South African businesses and professionals to build holistic cybersecurity strategies that include remote work environments and home networks.

Keeping your children safe online isn’t just a parenting win,  it’s a professional responsibility, too.
By following these steps, you’re not only protecting your family, you’re protecting your workplace and the broader digital community.

In today’s hyper-connected world, cybercriminals are no longer working from basements, they’re running sophisticated, professional operations targeting businesses of all sizes, especially here in South Africa.

And the threat is growing.

In 2025, we’re seeing a sharp rise in attacks on:

• Cloud systems
  
• Remote working devices
  
• Unsecured Wi-Fi and networks

While large corporations have dedicated security teams, SMEs are often left exposed, relying on outdated systems or minimal protection,yet they are just as much of a target.

Ask Yourself These 3 Questions:

1. Is your data encrypted?
   If not, it’s vulnerable, whether it’s stored in the cloud, on laptops, or in emails.
   
2. Are your systems monitored in real-time?
   Delayed responses mean greater risk. Active monitoring helps catch threats before they cause damage.
   
3. Do your staff know how to spot a phishing scam?
   Cybersecurity is not just a tech issue, it’s a people issue. Human error remains the #1 cause of data breaches.

The Good News? Protection Doesn’t Have to Be Complex

At Summit Networks, we work with local businesses across Johannesburg and beyond to implement cybersecurity strategies that are practical, scalable, and built for the real world.

We help you with:

• Securing cloud systems
  
• Protecting remote work devices
  
• Monitoring threats in real-time
  
• Training your team to be cyber-smart
  
• Creating response plans so you’re never caught off guard
  

Whether you’re a growing SME or a well-established enterprise, your digital safety matters and it starts with taking action before the breach, not after.

The post Cybercriminals Are Evolving — And So Should Your Defences first appeared on Summit Networks.

When we think about cybersecurity, most people picture hackers in hoodies, firewalls, or sophisticated software systems. But the reality is often much simpler, and far more human.

In many South African businesses, the biggest cyber risk isn’t a hacker breaking through your defences. It’s an employee accidentally letting them in.

From clicking a suspicious link to sharing confidential information on unsecured platforms, human error remains the number one cause of cybersecurity breaches. And with phishing attacks and social engineering on the rise, your team could be your greatest vulnerability—or your first line of defence.

Here’s how to turn your team from your weakest link into your strongest cybersecurity asset:

1. Cybersecurity Training That Sticks

Regular, interactive training is essential. Your staff should know how to:

• Spot phishing emails
  
• Avoid suspicious downloads
  
• Create strong passwords
  
• Report potential breaches immediately
  

Don’t just send out a PDF. Run hands-on workshops, simulate real-world scenarios, and make cybersecurity a regular part of your business culture.

2. Implement Two-Factor Authentication (2FA)

Even the strongest passwords can be stolen. 2FA adds an extra layer of protection by requiring a second verification step, like a code sent to your phone. It’s simple, cost-effective, and stops many attacks in their tracks.

3. Limit Access With Strong Controls

Not everyone needs access to everything. Set up role-based access to files, folders, and systems. That way, if one account is compromised, the damage is contained.

Think of it as digital compartmentalisation, a principle used by military and intelligence agencies to reduce risk.

4. Run Simulated Phishing Attacks

Put your team to the test with fake phishing emails. See who clicks, then use those results to coach and correct. It’s not about shaming… it’s about educating and building day to day habits that keep your data safe.

5. Create Clear, Easy-to-Follow Policies

Every team member should know:

• How to handle sensitive data
  
• Which devices can be used for work
  
• What’s safe to download or share
  
• Who to contact in a suspected breach
  

Your policies should be accessible, jargon-free, and reinforced regularly.
