An Email DLP solution helps organisations prevent sensitive data within email from being lost, leaked, misused or accessed by unauthorised individuals. It monitors outbound messages and searches for any content or attachments that may be sensitive, confidential, private or protected by regulation. When a message that contains sensitive data is found, email DLP systems may flag it, block it or delete it based on security policies.

Since email is a predominant form of business communication, Email data loss prevention is now considered an essential data security technology. Email DLP solutions are designed to help address the many potential causes of data leaks and loss, including cyberattacks, malicious insiders, security negligence and human error.

Some key features of Forcepoint DLP for Email are:

• Managing policies from one dashboard
• Effortlessly integrating with Microsoft and Gmail
• Maintaining data sovereignty and integrity

With a DLP for email solution, such as Forcepoint DLP for Email, organisations can get control over data by extending policy coverage to outbound emails. More specifically, it provides agentless control over outbound emails and prevents exfiltration where it's needed most.

DLP for email works by inspecting messages and attachments to look for content that may represent a potential data threat. Techniques to identify sensitive information and then take action may include the following: 

• Rule-based searches
• Exact matches
• Pre-built categories
• Flagging the situation
• Blocking the action
• Deleting the message

Email messages and attachments may contain a variety of sensitive material, including credit card information, intellectual property, financial data and more. Given the importance of safeguarding sensitive information in emails, DLP for email helps protect data against threats such as the following: 

• Inadvertent leaks
• Insider threats
• Cybercriminals

Absolutely. With Forcepoint DLP for Email, organisations can easily deploy on major email providers such as Microsoft Exchange, Gmail for Business and others.

A secure email gateway helps protect your business from malicious content contained within emails by preventing them from reaching their intended recipient.

Secure email gateways offer protection against malicious messages and attachments. By using robust email security solutions, organisations can dramatically reduce the number of successful and attempted attacks against their business.

A secure email gateway offers a robust framework of technologies that protect against email-borne threats. Most secure gateways offer a minimum of four security features: virus and malware blocking, spam filtering, content filtering and email archiving.

Forcepoint provides two distinct deployment options for email data loss prevention: cloud-native (SaaS) and on-premises. The cloud-native option runs on AWS infrastructure, offering scalability and 99.99% uptime with no scheduled downtime. The on-premises deployment retains full control over sensitive data, so organisations can comply with strict local sovereignty laws. Both deployments fully leverage Forcepoint's DLP policy engine and integrate seamlessly with all major email platforms.

Forcepoint's Email DLP solutions support specialised data security actions unavailable in Endpoint DLP. These include quarantine, encryption and drop attachment, enabling precision in stopping sensitive data exfiltration. Additionally, administrators can customise actions with x-headers for granular control. This high-precision framework ensures secure handling of emails containing sensitive, regulated or proprietary information.

With over 1,700 pre-built policies, classifiers and templates, Forcepoint's Email DLP solutions minimise false positives and streamline enforcement across cloud, web, endpoint and email. Using the Data Security Everywhere architecture, policy and incident management are unified in one console — allowing up to 31% savings in operational costs while improving accuracy and speed across enforcement touchpoints.

Yes. Forcepoint's Email DLP supports configuration across multiple email domains, making it ideal for enterprises with multi-brand or regional email structures. Administrators can easily add or remove domains via the management console and choose MTA recovery sources (e.g., O365, GSuite). This flexibility supports complex environments without compromising control or visibility in enforcing email data loss prevention.

While Section 33 of Hong Kong’s Personal Data Privacy Ordinance (PDPO) is not yet in force, the Office of the Privacy Commissioner for Personal Data (PCPD) recommends that organisations adopt best practices for cross-border data transfers. These include implementing contractual safeguards, such as the Recommended Model Contractual Clauses (RMCs), to ensure that personal data transferred overseas receives protection comparable to that under the PDPO.

Forcepoint Email DLP solution aids compliance by offering granular policy controls, selective encryption and hybrid deployment options. These features allow organisations to inspect, route or quarantine sensitive email content based on jurisdiction-specific requirements — thereby supporting secure and compliant cross-border operations without compromising operational efficiency.

Hong Kong businesses face distinct cybersecurity challenges, including a surge in cyber breach incidents and a basic level of cybersecurity readiness. Forcepoint Email DLP addresses these issues through advanced threat detection and prevention mechanisms. Its features include real-time monitoring of email communications, identification of sensitive data and enforcement of security policies to prevent data exfiltration. By integrating with existing email systems and providing granular control over data flows, Forcepoint Email DLP enhances the security posture of Hong Kong organisations against prevalent cyber threats.
