Email Is Still the Entry Point for Most Cyberattacks
If there’s one thing that hasn’t changed in the cybersecurity landscape in recent years, it’s this: email remains attackers’ favorite tool. According to the latest data from international reports, over 90% of successful cyberattacks start with a simple email message. And this applies equally to small businesses, large corporations, and public sector organizations and ministries alike.
Phishing isn’t what it used to be. We’re not talking about crude messages from unknown foreign princes anymore. Today’s attacks are targeted, professionally worded, and often impossible to distinguish from legitimate correspondence. Spear phishing, business email compromise (BEC), and quishing via QR codes are just a few of the techniques being used systematically against Greek businesses.
What Makes Phishing So Dangerous Today
The answer is simple: it has become extremely personalized. Attackers spend time studying the target company, its employees, its suppliers, and even its internal procedures. An email that appears to come from the CEO to an accounting employee, requesting an urgent transfer of funds, is not a rare scenario. It’s a daily reality.
Additionally, the widespread use of artificial intelligence tools has made creating convincing phishing content far more accessible to malicious actors. Spelling mistakes and suspicious phrasing, which used to be warning signs, now rarely appear.
The Consequences for a Business Can Be Devastating
A successful phishing attack can lead to compromised corporate accounts, credential theft, ransomware, leakage of sensitive customer data, or even financial fraud. For businesses subject to GDPR or other regulatory frameworks, the consequences extend to the legal level as well, with fines and damage to the company’s reputation.
In public sector and governance environments, the exposure is even greater, as citizen data or critical infrastructure may be affected.
Practical Steps You Can Take Now
Protection against phishing isn’t a matter of luck. It’s a matter of structure and prevention. Here’s what you can implement right away:
Enable MFA everywhere: Multi-Factor Authentication is one of the most effective barriers you can put in place. Even if credentials are stolen, access remains impossible without the second factor.
Implement email filtering and anti-phishing policies: Solutions that inspect incoming messages at the content, link, and sender level can stop the threat before it reaches the user.
Train your people: Technology alone is not enough. Employees need to know how to recognize suspicious messages and what to do when they encounter them. Simulated phishing campaigns are a practical way to assess and improve readiness levels.
Implement DMARC, DKIM, and SPF: These email authentication protocols help prevent your domain from being used by third parties for spoofing attacks.
Have a response plan: If something goes wrong, you need to know exactly what the next steps are. Who gets notified, how the incident gets isolated, how recovery happens.
Technology and Experience Make the Difference
Protecting against phishing and broader email threats requires a combination of the right tools, proper configuration, and experience. At Cyberstack, leveraging solutions from our partners such as Microsoft, Bitdefender, Fortinet, Safetica, and others, we design and implement email security strategies tailored to the needs of each organization, from small businesses to public sector entities and enterprise environments.
There’s no universal solution that fits everyone. What matters is correctly assessing the risk, choosing the right tools, and maintaining continuous monitoring.
Email Security Is Not a Luxury, It’s a Necessity
If your business doesn’t yet have a comprehensive email security policy, now is the right time to change that. Not when the incident happens, but before. Prevention costs far less than dealing with a breach, in money, in time, and in reputation.
