Shadow AI is sneaking into workplaces, risking data leaks and fines.

57% of employees admit to hiding the use of tools like ChatGPT.

Their biggest crime? Wanting to be more productive.

But IBM warns that the average cost of a Shadow AI breach in 2025 is $670K. And this doesn't include the fines for non-compliance.

Don’t let Shadow AI sink your business. Watch our latest video with expert strategies to secure and harness AI:

What should #AI NEVER do?

AI is transforming, well, everything... This means both securing your AI, and securing yourself from AI, has become a reality.

But where should you start?

In the latest episode of Security Beyond The Checkbox, we explain that the foundation of AI security lies in governance and in frameworks like ISO 42001 and NIST AI RMF.

However, today, these standards are so robust that it's doubtful the government would even pass an audit.

For SMBs, the key is to start small, focus on clear policies for data quality, access control, and monitoring.

While standards like ISO 42001 offer comprehensive guidance, simpler approaches, such as adopting zero-trust principles, can make AI security manageable without large budgets.

In 2025, ransomware and phishing remain headline-grabbers. But the real danger lies in subtler, more insidious shifts in attack patterns...🧵

6/ Phishing And Vishing
Business email compromise (BEC) and credential theft via phishing and vishing are skyrocketing, with 74% of data breaches involving the human element.

Attackers no longer rely on generic phishing emails. They craft advanced, tailored campaigns using publicly available data from LinkedIn profiles, corporate websites, or your “About Us” pages.

They’ll scan your network for vulnerabilities, then target specific business units.

For example, your finance team might receive a fake invoice from a “known vendor,” or an employee might get a vishing call from “IT” requesting a password reset.

In advanced cases, attackers will deploy tactics to throw their victims off guard, such as attempting to get them to reply to a phishing email. Or, they will phish the user, leveraging multiple accounts and attack scenarios.
