Google Workspace boasts over 8 million paying customers, a number that continues to rise. It’s not just the large user base that stands out, but also the impact on productivity.

Spambrella email security tools for Google Workspace for 2025

User synchronization with Spambrella/Proofpoint Essentials

Many will know that Proofpoint Essentials does not directly integrate with Google Workspace to sync user directories. Spambrella has developed an industry-first user directory sync for Proofpoint Essentials with Google Workspace. The integration can only be accessed if you are an MSP partner or customer of Spambrella for Proofpoint services. Spambrella continues to innovate with new tools and features to elevate your use of Proofpoint Essentials.

Our ability to automate tasks for admins and end users simplifies and amplifies the user experience.

Can I use the Spambrella Proofpoint Essentials Google Workspace sync via my Distributor?

The Spambrella team is a development and global support partner to Proofpoint. Our Proofpoint distribution (pre- and post-sale) is extended to Cloud Marketplaces and some of the largest IT Distributors working with the Proofpoint Essentials service. If you wish to access the Spambrella, Proofpoint Essentials, Google Workspace Sync feature, contact your Distributor (if you are a Proofpoint partner).

If you are an existing Proofpoint customer, contact your account manager or the Spambrella technical support team for more information. If you are not already a partner/customer of Spambrella for Proofpoint services, migrating your account so you can access the synchronization is a simple process.

Google Workspace Phishing Protection & URL Defense

Google Workspace puts phishing messages with bulk mail and spam into the end user’s email junk folder, which can be accessed through the Google Message Center. This forces the end users to make split-second security decisions – ‘Is this bulk mail that I signed up for or is this a targeted attack?’. Spambrella’s email security solutions for Google Workspace use advanced machine learning technology to detect phishing messages and perform a unique action on them.

Spam Detection, Effectiveness, and Accuracy

Spambrella uses Proofpoint’s advanced machine learning technology to granularly and more accurately detect spam (unsolicited bulk mail) and solicited bulk mail. This allows administrators to configure Google Workspace spam filtering policies so that end users have access only to specific types of spam: eg, a quarantine that contains only bulk mail, a quarantine that contains only adult spam, and a quarantine that only contains spam. The efficacy of the service and its detection rates are of the highest calibre and considered best of breed within the industry.

Outbound Email Data Loss Prevention

How much time does your organization spend manually creating Google Workspace data loss prevention policies? Or, does your organization require end users to manually trigger encryption? A recent survey by the Ponemon Institute showed that employees mistakenly send unencrypted confidential information to other recipients outside the workplace on a regular basis (63% of their respondents). It is more than likely time for you to consider a re-evaluation of your compliance policies.

Google Workspace Email Encryption

One of Spambrella’s major values for Google Workspace is the addition of user-level policy-based encryption. Spambrella provides controls to administrators to manually apply rules by content or recipient, which automates the encryption process on the fly. Smart identifiers (regex) are included within custom filters and can be applied inbound or outbound to secure email in Google Workspace.

The smart identifiers range from financial information (Credit Card number detection) to HIPAA/Healthcare identifiers. For the EU market, Google Workspace users can make use of the GDPR smart filters.
