How to secure Google Workspace for your business?

What does “Properly Securing” Google Workspace mean?

You use Google Workspace every day to communicate, collaborate, and store your important files. But have you ever taken the time to check if your environment is truly well-protected?

The good news: Google takes care of infrastructure security. The responsibility that falls on you is to correctly configure access and adopt good habits. In other words, Google installs the locks—it’s up to you to decide who gets a duplicate key.

In this article, we explain the essential elements to put in place, without the technical jargon, so you can sleep soundly at night.

Who can access what in your organization?

The first thing to secure is your employees’ identity. If a single account is compromised, your entire organization is potentially exposed. Here are the three most important habits to adopt:

→ Enable 2-Step verification

Imagine a safe that opens with a key AND a secret code. Even if someone steals the key, they can’t get in without the code. That’s exactly what 2-step verification does: even if a password is guessed or stolen, no one can access the account without an additional confirmation (on the employee’s phone, for example).

For your most sensitive accounts—such as administrators or human resources—there are even physical security keys (like a small USB key) that offer even stronger protection.

→ Opt for passphrases rather than complex passwords

Passwords filled with numbers and special characters always end up on a sticky note under the keyboard. Instead, encourage your teams to use simple, memorable phrases: “MyCatRockyEatsAnApple!” is much harder for a hacker to crack, and much easier for a human to remember.

→ Protect your domain against spoofed emails

There are email settings your administrator can configure to ensure no one can send an email pretending to be your company. Google Workspace also automatically displays a warning banner when an outsider uses a name identical to one of your employees—a detail that prevents many traps.

Are your files sharing too much information?

Data leaks, whether caused by a malicious employee or a simple human error, are the most common risk businesses face. Here is how Google Workspace helps you keep them under control.

 
Decide who can see what

By default, it is tempting to share everything with “everyone in the company.” However, this can quickly become problematic, especially now that artificial intelligence tools can scan and surface documents, including those that certain employees should not be able to access. The best practice: Create groups by team or project, and share exclusively with the right people.

 
Block sensitive information from leaving the organization

Enterprise licenses include an automated detection system that monitors your files and blocks suspicious sharing. If an employee tries to email a document containing credit card numbers or medical information, the system automatically stops it. It’s like having a security guard check the contents of every package before it leaves the building.

 
Separate teams based on data sensitivity

Enterprise licenses also allow you to create “walls” between departments. For example, the HR team is automatically prevented from sharing employee files with other departments, without having to think about it every time. This is an essential feature for complying with regulatory obligations like Quebec’s Law 25.

 
Restrict access based on context

You can easily define simple rules such as: “No one can access files from a foreign country” or “Only company-issued devices are authorized.” An employee logging in from a café while on vacation using a personal laptop can represent a risk; this type of rule blocks them automatically.

How to monitor what happens in your Workspace?

Good security isn’t something you configure once and forget about. It requires continuous vigilance. Fortunately, Google Workspace provides your administrator with the tools to keep an eye on everything without spending all day looking at screens.

1. 1. Reports to understand who is doing what

   Your administrator can review a history of logins, file shares, and setting modifications. This is ideal for quickly spotting unusual activity from an unknown device. The admin can also send you direct feedback to optimize your security or correct a setting.

2. 2. Automated alerts for quick responses

   There is no need for constant monitoring: the system alerts you within minutes if something suspicious occurs. You can be notified immediately about emails that look like phishing attempts, an unusual volume of downloads, a login from a new device, and other customizable parameters.

3. 3. Control Over Connected Apps

   Employees sometimes connect third-party applications to their Google accounts without informing the IT team. Some of these tools can access your data. The administrator can view the complete list of these connections and block those that pose a risk.

A security audit: Why and how does it work?

Thinking your environment is well-protected is one thing. Rigorously verifying it is another.

A Google Workspace Security Audit is an in-depth analysis of your current configuration. We check hundreds of settings, identify hidden vulnerabilities, and provide you with a clear report featuring concrete recommendations.

The goal is not to lock everything down to the point of slowing your team down. It is to find the right balance between security and day-to-day workflow efficiency.
