Is your business safe from the inside? The rise of the rogue tech expert
Most owners worry about hackers halfway across the world. However, the most dangerous person might be sitting right next to you. Insider threats have evolved beyond accidental data leaks. We are now seeing trained IT staff actively working with cybercriminals for profit. There’s nothing that firewalls can do when the attacker already holds the key to the building.
The fox in the henhouse
A skilled insider threat is far more dangerous than an external hacker. An outsider has to spend days or weeks probing your defenses to find a weakness. A rogue IT professional already knows where the weaknesses are. They possess the administrative passwords, they know where your backups are stored, and they understand exactly how to disable your security alerts.
Recent news highlights a disturbing shift in cybercrime. Prosecutors are uncovering cases where cybersecurity professionals are not just ignoring threats but actively collaborating with ransomware gangs. These insiders can install backdoors that allow criminals to enter your system undetected. Because they know the layout of your network, they can help attackers cause maximum damage in minimum time.
Small businesses are easy targets
You might think your business is too small to attract this kind of sophisticated trouble. That assumption is dangerous. Criminals often target smaller companies precisely because they lack the complex layers of oversight found in major corporations.
Big companies usually have large security teams where employees watch each other. If one administrator acts suspiciously, another one can flag it. Small businesses rarely have that luxury. You likely rely on a single IT employee or a small external agency for everything. That creates a single point of failure. If that one person turns against you, they can hold your data hostage or wipe your servers before you even realize something is wrong. The cost of such a betrayal is often higher for small businesses because you may not have the resources to survive a weeks-long shutdown.
Limit the master keys
You don’t need to be a tech wizard to fix this. Start by changing how you handle access. In the security world, we call this the principle of least privilege.
Think of it like a physical building. You do not give the janitor the keys to the safe, and you do not give the intern the alarm codes. Apply that same logic to your computers. Only give employees access to the specific files and systems they need to do their jobs. Even your IT staff should have restrictions. If they don’t need to access your financial records to fix the printer, they shouldn’t have that access.
Verify your experts
Treat your IT consultants and employees like any other sensitive hire. Technical skills are important, but character matters more. Run background checks and ask for references. If you use an outside IT company, ask them how they vet their own staff. You have the right to know who is walking through your digital front door.
Keep offline backups
Ransomware attacks work because the criminals lock your files and demand money to unlock them. A rogue insider will often try to delete your backups first so you have no choice but to pay.
Defeat this tactic by keeping an offline backup. This is a copy of your data stored on a hard drive that is physically unplugged from the network, or a cloud service that your main IT admin cannot delete. If your system gets wiped, you can simply plug in the drive and restore your business without paying a cent.
Watch for warning signs
You don’t need to read code to spot trouble. Set up simple alerts or ask for weekly reports that show who is accessing the system. Look for odd behaviors, such as a user logging in at 3:00 a.m. or downloading massive amounts of data on a weekend. If your IT provider can’t explain why these things are happening, you need to investigate immediately.
Trust but verify
Technology keeps your business running, but human judgment keeps it safe. You can respect your IT team without giving them unchecked power. By setting clear boundaries and keeping a close eye on your “keys,” you protect your livelihood from the few bad apples who might try to exploit it.
Take action quickly. Ask your IT person or provider who has administrative access to your network and request a log of their recent activity. The simple act of asking shows you are paying attention.

We give our IT teams the keys to the kingdom to keep operations running. Yet, that access creates a massive blind spot. Recent trends show disgruntled tech workers bypassing the very security measures they helped build. Trust is necessary for business, but blind faith in your technical staff leaves your company wide open to attack.
Picture the person you call when your email breaks. You likely trust them with every password you own. But what if that person used their skills against you? Security threats are no longer limited to clumsy employees clicking bad links. Now, they include skilled professionals intentionally opening doors for criminals. Technical expertise does not always equal honesty.

With cyberthreats evolving faster than traditional update cycles, Apple has retired its Rapid Security Response in favor of a more granular approach: Background Security Improvements. This shift aims to minimize the attack surface by automatically and silently patching vulnerable components such as WebKit, keeping devices fortified without user intervention.
Gone are the days of waiting for a full OS update to address urgent vulnerabilities. With Background Security Improvements, Apple devices can now automatically and discreetly remain protected in real time, redefining what it means to stay secure in today’s ever-evolving digital landscape.
Keeping up with digital threats means staying one step ahead, and Apple is doing just that. The latest updates to iOS, iPadOS, and macOS introduce Background Security Improvements, which is a smarter, faster way to install critical fixes in the background without requiring your input. This innovation enhances security for users and businesses alike without the interruptions that come with traditional updates.
Businesses that once adopted Voice over Internet Protocol (VoIP) to save money and improve call quality are now tapping into something even more powerful: artificial intelligence (AI). AI is being woven into communication systems to not just support calls, but to understand, adapt, and learn from them, making conversations smarter and customer service more seamless.
