If you run a business, an employee can easily email your client list to their personal account, whether by accident or on purpose.

Most companies just trust their staff not to do this.

But you need a technical rule that stops sensitive data from leaving your network in the first place.

If you use Microsoft 365, you can use a tool called Microsoft Purview to set up Data Loss Prevention rules.

When you turn this on, the system scans every outgoing email, Teams messages, SharePoint/OneDrive files, endpoint devices, browser activity, and Microsoft 365 Copilot prompts before processing.

If it detects sensitive information like Social Security numbers, credit card details, or specific internal company tags, it physically blocks the email.

You do not have to monitor employees manually.

Subdomains can be a cybersecurity risk.

If you use subdomains, you might be accidentally giving hackers permission to use your exact website address.

Think about the temporary marketing campaigns, event pages, or third-party software portals you set up in the past.

Usually, companies create a custom web link for these projects, like promo.yourcompany.com

To make it work, that custom link is connected to an external hosting service.

When the project ends, you probably cancel the external hosting subscription to save money.

But the connection rule in your website settings is almost never deleted.
This creates a massive blind spot.

Attackers constantly scan the internet for these abandoned connections.

When they find one, they go to that exact hosting company and register the account name you used to have.

Because your website is still pointing there, the attacker instantly takes control of your official custom link.

They can now send phishing emails to your clients or host scam pages that look completely real.

Your clients will trust the link because it literally uses your actual company name.

If you haven’t done this yet, you need to audit your website DNS records as soon as possible.

Delete any custom links pointing to software or services your business no longer uses.

Don’t treat Microsoft OneDrive or Google Drive as a guaranteed backup.

Many people assume that if their network gets hit by ransomware, they can just log into their cloud account and restore an older version of their files.

The problem is that modern ransomware can sync encrypted files to your cloud account, overwriting clean versions and potentially targeting version history or recycle bin contents before you even realize you have been attacked.

When malicious software reaches a synced laptop, the damage does not stay on that single device.

Because your cloud drive is designed to sync changes instantly, the system automatically uploads those locked, encrypted files straight into your company cloud.

It directly overwrites your clean data.

Cloud storage connects your data, without isolating it.

To have a higher level of security, you need a separate backup system that is completely offline or locked down.

You need an isolated copy of your files that a compromised network account cannot reach, alter, or delete.
