Question 1

What types of data loss can Mimecast prevent?

Accepted Answer

Mimecast helps prevent both accidental and intentional data loss by humans and
AI agents across email, endpoint, browser, cloud, and agentic. This includes
sensitive files shared via email, data pasted or uploaded to GenAI tools, an AI
gent reaching into systems like source code, intellectual property exfiltrated
during employee offboarding, and regulated data like PCI, PII, HIPAA, or GDPR
information leaving the organization.

Question 2

How does Mimecast address data loss through AI tools and AI agents?

Accepted Answer

AI tools and agents have become a major new channel for data loss: employees
paste sensitive data into public chatbots, and AI agents connect to systems like
source repositories, data warehouses, and production databases to act on an
employee's behalf. The Mimecast solution treats this as an extension of the data
protection program you already run rather than a separate tool. It discovers the
AI tools, agents, and MCP connections in your environment, maps which ones can
reach sensitive data, ties each agent to the human who deployed it, and applies
response controls that range from nudges to blocking uploads and pastes to
unsanctioned AI destinations. Because an agent inherits the privilege of whoever
deployed it, the person behind the agent is central to Mimecast's approach: the
same activity carries different risk depending on who is behind it.

Question 3

What is shadow AI, and how does Mimecast help?

Accepted Answer

Shadow AI is the use of AI tools, agents, or workflows without IT or security
approval. It is the AI equivalent of shadow IT, except that these tools can
actively process and move sensitive data at machine speed. The Mimecast solution
surfaces shadow AI by discovering every AI tool, agent, and connection as it
appears, with no policies to write first. Teams can then classify what is
sanctioned versus unsanctioned, prioritize the departments where risk
concentrates, and apply targeted controls instead of blocking AI outright, so
the organization can enable AI use safely rather than shutting it down.

Question 4

How is Mimecast's DLP different from traditional data loss prevention tools?

Accepted Answer

Mimecast pairs policy-based email DLP with the Mimecast solution's behavioral
analytics, replacing static content-matching rules common in traditional DLP
with real-time context. Instead of keyword matches that demand constant tuning
and flood teams with false positives, the Mimecast solution monitors how data
actually moves across email, endpoints, browsers, cloud apps, and now the AI
tools and agents employees use. It prioritizes events automatically by user,
destination, and source.

Question 5

How does Mimecast address insider risk without disrupting employee productivity?

Accepted Answer

The Mimecast solution is a data protection solution that monitors file activity
in the background without blocking normal collaboration, using an
ultra-lightweight endpoint agent, browser extension, and cloud connectors. It
uses behavioral context to distinguish routine work from genuinely risky
activity, and can nudge users in real time or block high-risk scenarios,
balancing security and productivity. That same lens now extends to AI agents:
because an agent inherits the access and privilege of the person who deployed
it, Mimecast ties each agent to that human, so you can see the person behind the
activity, not just the action itself.

Question 6

How quickly can Mimecast's DLP solution be deployed?

Accepted Answer

Because the platform is cloud-based and the Mimecast solution doesn't depend on
predefined content policies to start detecting risk, organizations can gain
visibility into data movement within hours or days, not the weeks or months
typically required by legacy DLP solutions. There's no policy setup required to
get visibility into unsanctioned data movement, so teams see activity as soon as
the endpoint agent and browser extension are deployed. The AI tool and agent
discovery capabilities run on that same endpoint agent and browser extension, so
there is no separate deployment or proxy infrastructure to stand up for AI
visibility.

Question 7

What should I do if I discover an employee is leaking sensitive data?

Accepted Answer

Contain the risk immediately by revoking access and isolating affected devices
using built-in EDR and IAM integrations. Review the incident using the Mimecast
solution's detailed activity logs, including file preview and download
capabilities, to understand what data was moved, where it went, and whether it
was intentional. Escalate to your legal and HR teams as needed, and use the
findings to strengthen policies and response workflows.

Question 8

How does Mimecast's Email DLP work?

Accepted Answer

Mimecast scans outbound email content, attachments, subject lines, and metadata
using content policies, pattern matching, and document fingerprinting. When a
policy violation is detected, Mimecast can block the message, quarantine it for
review, or route it through secure messaging automatically.

Question 9

What happens when an Email DLP policy is triggered?

Accepted Answer

Depending on your configuration, Mimecast can block the email, hold it for
administrator review, send it via secure messaging, or strip sensitive metadata
from attachments. These actions are automated and customizable by user, group,
or content type.

Question 10

Can Mimecast protect data beyond email?

Accepted Answer

Yes. Beyond email, the Mimecast solution extends data protection by monitoring
file activity across email, endpoint, browser, cloud and agentic. Giving you one
view with full context across all risk channels.

Question 11

Does Mimecast support regulatory compliance?

Accepted Answer

Mimecast helps organizations meet requirements for GDPR, HIPAA, PCI-DSS, and
other frameworks by enforcing content policies on sensitive data, providing
tamper-proof evidence of policy violations, and securing how regulated
information is shared. As AI-specific regulation arrives, including the EU AI
Act, DORA, and standards like ISO 42001, the Mimecast solution helps here too,
giving teams a day-one inventory of the AI tools and agents in their environment
and a record of what those tools can reach and who approved them. Mimecast was
the first cybersecurity company to achieve ISO 42001 certification for AI
management systems, in January 2025.

Question 12

Can Mimecast's DLP solutions integrate with Microsoft 365?

Accepted Answer

Yes. Mimecast integrates with Exchange and Microsoft 365 as a specialized
security layer, applying DLP policies to all outgoing email without disrupting
existing workflows or requiring users to change how they send messages. The
Mimecast solution can also ingest Microsoft Purview MIP tags for visibility.

Question 13

How does Mimecast handle secure file sharing in email?

Accepted Answer

Mimecast Large File Send lets users share files up to 2 GB securely while
enforcing DLP policies. This gives employees a safe alternative to unsanctioned
file-sharing services and keeps sensitive transfers under organizational
control.
