Microsoft 365 and Google Workspace are now common tools for businesses of every size. Email, documents, calendars, meetings and many other daily tasks run through these cloud platforms. Microsoft and Google provide security options that protect business accounts. If a company relies only on the default settings, important gaps may remain.
The problem is not that Microsoft 365 or Google Workspace are unsafe. The bigger issue is that many businesses do not set up the security controls to match their risks. Phishing, account takeover, accidental data sharing and data loss can still occur when a company uses Microsoft 365 or Google Workspace with minimal security hardening.
Understanding where these gaps exist can help a company build stronger cloud security while keeping everyday work easy.
Why Default Microsoft 365 and Google Workspace Settings May Not Be Enough
Default settings are designed to provide a level of protection for a wide range of users. They cannot cover every company’s users, devices, applications, data and work habits.
Phishing is one example. An employee may get an email that looks like it comes from a supplier, customer or manager. If an attacker can obtain the login details, the attacker may gain access to email, files and other connected services.
Account takeover can become more serious when a compromised account can access sensitive information or send convincing messages to other employees.
Businesses that use Google Workspace can review their configuration and security controls through Google Workspace support, while Microsoft 365 environments can be hardened to match the organisation’s users, devices and security needs.
Hardening the Most Important Security Controls
Cloud security does not always require changing every setting in Microsoft 365 or Google Workspace. A better approach is to identify the controls that can reduce the biggest risks.
Use Stronger MFA Methods
Multi-factor authentication adds another layer of protection when a password is stolen. However, not every MFA method provides the same level of resistance to modern attacks.
A company should consider stronger authentication methods where appropriate and review how users can authenticate from different devices and locations. Security policies should also cover administrators, remote workers and accounts that have access to sensitive information.
Control Access Based on Risk
Access policies can help a company decide when users should be allowed to access business resources. For example, access rules can differ for a trusted company device compared with an unmanaged device.
This type of access control can reduce the damage caused by stolen credentials because simply having the correct password may not be enough to gain access.
Improve Link and Attachment Protection
Malicious links and attachments are still common ways to deliver phishing attacks and malware. A company should use the security features available in its cloud platform to check links, attachments and messages.
Security settings should also be reviewed regularly because attackers change their methods over time.
Review External Sharing
Cloud collaboration lets a company share files with customers, contractors and other external contacts. However, unlimited external sharing can create unnecessary exposure.
A company should check who can share files externally, whether anonymous links are allowed and how access is removed when it is no longer needed.
Device posture is another factor. A user who accesses company data from an outdated device can create a different level of risk compared with a user who works on a properly protected company device.
Email Security Goes Beyond Microsoft 365 and Google Workspace
Even with strong platform security, a company should not treat email security as a single setting.
Domain-based protections such as DMARC can help a company reduce email spoofing and make it harder for attackers to impersonate the company’s domain. SPF and DKIM are also part of the email authentication process.
DMARC enforcement is especially important for a company whose domain is often targeted by impersonation attempts. A company should know which legitimate services send email on its behalf before moving to stricter enforcement.
Additional managed email security services can also provide another layer of filtering and protection. These services can be useful when a company has needs that go beyond the standard protection available in its cloud platform.
For a company concerned about domain-level threats, advanced domain security services can be part of an email and cyber security plan.
Backup Still Matters in SaaS
Many people think that because Microsoft 365 and Google Workspace are cloud services, business data is automatically backed up like it would be on a traditional server.
Cloud platforms provide availability and data protection, but availability is not the same as having an independent backup of business data.
Think about a case where an employee accidentally deletes important files, an account is compromised, data is deliberately removed, or a business needs to recover information from an earlier point in time. Depending on the circumstances and retention settings, the platforms’ built-in recovery options may not provide everything the business needs.
This is why independent SaaS backup remains relevant.
The traditional 3-2-1 backup approach can still provide a useful framework: keep multiple copies of important data, use different storage types or locations, and keep at least one copy separate from the primary environment.
For Microsoft 365 and Google Workspace, this can include protecting mail, Drive or OneDrive files, Teams-related data and other important business information. A broader managed backup service can help businesses plan retention and recovery around their requirements.
Closing the Loop With Managed Cloud Services
Security is not a one-time configuration exercise. User accounts change, employees leave, devices are replaced, applications are added and business requirements evolve.
This is where managed cloud services can help. Regular administration can include reviewing security policies, managing users, monitoring configurations and helping businesses respond to changes.
Migrations are another important part of the process. Moving from one platform or environment to another without proper planning can create security, data and access problems. Businesses can use structured Microsoft 365 migration support or Google Workspace migration support to plan the transition and reduce disruption.
Licensing also deserves attention. Businesses sometimes pay for features they do not use while missing features that could improve security or administration. Reviewing licences alongside security requirements can help organisations make informed decisions.
A More Complete Approach to Cloud Security
Microsoft 365 and Google Workspace provide a strong foundation for modern business operations, but the default configuration should not automatically be treated as a complete security strategy.
A complete approach combines MFA, access controls, phishing protection, external sharing policies, device security, DMARC, email protection and independent cloud backup.
Regular reviews are just as important. Security settings that were appropriate when a company had 20 employees may not be suitable after the business grows to 100 employees or introduces remote working.
The real cost of default security is therefore not simply the price of a security service. It can include lost access, disrupted operations, compromised accounts, exposed information and the time required to recover from an incident.
By reviewing Microsoft 365 and Google Workspace configurations, strengthening the areas that matter most and maintaining reliable backup and recovery processes, businesses can reduce these risks while keeping their cloud environment practical for everyday work.
