The uncomfortable truth is that CISOs believe their cyber perimeter is secure with technology, yet the real threat is your people. Human error causes 95% of breaches. What’s worse is that most cyber incidents result from preventable employee mistakes, such as clicking malicious links, reusing credentials, selecting weak passwords and mishandling sensitive data.
How CSG can help you build a human firewall
Businesses are investing more than ever in cyber security technology – firewalls, encryption, endpoint protection – but despite these efforts, cybercriminals continue to find their way in. Why? Because your biggest cyber security risk isn’t your technology, it’s your people.
Human error: the weakest link in cyber security
From clicking on phishing emails to using weak passwords or falling for social engineerings scams, employees (often unknowingly) open the door to cyber threats. In fact, 95% of data breaches in 2024 were linkedin human error, including insider threats, credential misuses and user-driven mistakes.
A real-world example of this includes the Change Healthcare ransomware attack, attackers gained access through a phishing email that compromised an employee’s credentials. This single lapse led to a massive breach that disrupted healthcare services across the U.S. and cost millions in damages.
Technology alone isn’t enough
Even the most advaned security systems can’t prevent a breach if an employee unknowningly hands over access. Cyber criminals are increasingly using AI-generated phishing emails and deepfake voice calls to trick users into revealing sensitive information.
In early 2025, a UK retail company was hit by a ransomware attack after an employee responded to a fake vendor email crafted using AI. The breach exposed customer data and halted operations for days.
Empower your people to be your first line of defence
At CSG we focus on empowering your people – because awareness and vigiliance are always your best defence. Cyber security in this day and age is everyone’s responsbility. Experts suggest to partner with a cyber security specalist to gain regular and ongoing training and awareness solutions that have been designed to transform your employees into a proactive, informed and vigiliant human firewall.
Cyber awareness through the latest phishing campaigns
Phishing is constantly evolving. Our intelligent training system uses real-life templates and scenarios based on the latest threat intelligence to keep your users sharp and prepared.
Example: in 2025, attackers used fake Microsoft Teams invites to deliver malware. Our training now includes simulations of such tactics, helping users recognise and report suspicious collaboration tool messages
Report phishing directly from Outlook and Office 365
With our phish threat outlook add-in, your employees can report suspicious emails with a single click, with no need to remember complex procedures. This not only empowers users but also gives your security team real-time visibility into emerging threats.
Example: during a simulated phishing campaign, one of our clients saw a 70% increase in reported threats after deploying the add-in – allowing our SOC team to neutralise risks before they escalated.
Awareness training that works
We offer a library of over 30 interactive training modules, covering both security and compliance topics. These include:
- Automated, on-the-spot training triggered by risky behaviour
- Engaging, scenario-based learning that sticks
- Available in 9 languages, making it more accesible for global teams
- Integrated testing and reporting to track progress and identify gaps
Example: a financial services client reduced phishing click rates by 82% within six months of launching our training program – demonstrating the power of consistent, relevant education.
Building a culture of cyber vigilance
Cybersecurity isn’t a one-time event, it’s a mindset. CSG helps you build a culture where security awareness is second nature. When your people are informed, alert and empowered, your entire organisation becomes more resilient.
We also help you identify high-risk users and provide additional support to them, because just 8% of employees are responsible for 80% of security incidents.
