Data leakage prevention has changed. For years, many security programs treated DLP as an internal control problem: stop employees from emailing sensitive files, uploading documents to unmanaged cloud apps, copying data to USB drives, or mishandling confidential information. Those controls still matter. But today, some of the most dangerous leaks happen outside the corporate perimeter, after credentials, tokens, cookies, customer data, or internal assets have already been stolen and traded across infostealer ecosystems, dark web marketplaces, Telegram channels, paste sites, and breach dumps.
That shift matters for organizations aligning to ISO/IEC 27002:2022. ISO/IEC 27002 provides guidance for selecting and implementing information security controls as part of an Information Security Management System. While ISO/IEC 27001 defines the certifiable ISMS requirements, ISO/IEC 27002 offers practical control guidance that organizations can use to manage information security risks.
The 2022 edition modernized the control set, organizing 93 controls into four themes: organizational, people, physical, and technological controls. Among these controls is ISO 27002 Control 8.12, Data Leakage Prevention, which focuses on detecting and preventing unauthorized disclosure or extraction of information.
This is where Lunar can play a strategic role.
Data leakage is no longer only an internal event
Traditional DLP tools usually focus on data movement inside the organization: files, endpoints, emails, SaaS applications, and network traffic. ISO 27002 Control 8.12 fits this world because it emphasizes prevention and detection of unauthorized data transfer through measures such as access controls, monitoring, encryption, and security tooling.
But modern attackers do not always need to break in through the front door. They often buy access that has already been leaked. Infostealers can harvest usernames, passwords, browser cookies, session tokens, SaaS logins, device identifiers, and other artifacts from both managed and unmanaged devices.
This creates a major gap in many DLP programs. An organization may have strong internal controls, but still lack visibility into whether its data, accounts, or access tokens are already exposed in criminal ecosystems. A mature DLP strategy therefore needs two layers: preventing data from leaving controlled environments, and detecting exposed data after it appears outside those environments.
Lunar extends DLP visibility beyond the perimeter
Lunar helps organizations close this external visibility gap by continuously monitoring compromised credentials, infostealer logs, breach dumps, combolists, marketplaces, and other sources where stolen access data appears.
This matters for ISO 27002 because Control 8.12 is both preventive and detective in nature. The control is not only about blocking data movement. It is also about identifying situations where sensitive information may be disclosed, extracted, or misused.
Lunar supports the detective side by alerting teams when organizational credentials, tokens, cookies, or related identity data appear outside the organization. It supports the preventive side by enabling security teams to act before attackers use those exposures for account takeover, lateral movement, business email compromise, or further data exfiltration.
In practical terms, Lunar turns external breach intelligence into a DLP signal. When a corporate credential appears in an infostealer log, that is not just a credential issue. It may indicate that business systems, customer data, internal documents, cloud resources, or email accounts are at risk of unauthorized access. Detecting that exposure early gives the organization a chance to prevent the next stage of leakage.
Mapping Lunar to ISO 27002 data protection controls
Lunar is most directly aligned with ISO 27002 Control 8.12, Data Leakage Prevention, but its value extends across several related controls.
Control 8.12, Data Leakage Prevention
Lunar continuously detects exposed credentials, passwords, tokens, cookies, and session keys tied to the organization. Its enriched alerts help teams understand what was exposed, where it appeared, and what action is required.
This supports a broader DLP strategy by identifying leaked access data before it can be used to reach sensitive systems or extract additional information.
Control 5.7, Threat Intelligence
ISO 27002:2022 introduced threat intelligence as a dedicated control. Lunar contributes to this area by collecting and contextualizing intelligence from breach dumps, infostealer logs, marketplaces, forums, Telegram channels, and other external sources.
Instead of relying only on generic threat feeds, organizations can use Lunar to identify exposure that is directly tied to their own domains, employees, systems, and digital assets.
Controls 5.24 to 5.28, Incident Management
Lunar helps transform external exposure into structured incident response. When leaked credentials or tokens are detected, security teams can use Lunar’s context to prioritize the event, assign ownership, and trigger remediation actions.
Those actions may include password resets, session invalidation, MFA enforcement, account lockouts, endpoint investigation, or escalation to incident response teams.
Control 5.34, Privacy and Protection of PII
When exposed data includes employee, customer, or partner identifiers, Lunar can help organizations detect privacy-related exposure earlier. This supports privacy and accountability programs by giving teams visibility into potential personal data risks that appear outside the organization.
Controls 8.15 and 8.16, Logging and Monitoring
Lunar’s alerts and integrations can feed external exposure events into existing security workflows, including SIEM, SOAR, IAM, identity provider, and ticketing systems.
This allows security teams to correlate leaked credentials or tokens with authentication logs, endpoint activity, cloud events, and other monitoring data.
Why external exposure intelligence strengthens DLP evidence
ISO 27002 is risk-based. It does not require every organization to implement the same tools in the same way. Instead, organizations are expected to select and operate controls based on their risks, assets, business context, and legal or contractual obligations.
For auditors and internal governance teams, the question is not simply, “Do we have DLP?”
A better question is:
Can we prove that we detect and respond to unauthorized exposure of sensitive information, including exposure outside our environment?
Lunar helps provide that proof. It can support evidence such as:
- Continuous monitoring of external sources for exposed organizational credentials and access artifacts.
- Risk-prioritized alerts showing what was exposed and why it matters.
- Forensic context, including malware family, device details, login URL, timestamps, and source context.
- Response records showing remediation actions such as password resets, session revocation, MFA enforcement, account lockouts, or escalation to incident response.
- Integration records showing that exposure intelligence is routed into existing security workflows.
That evidence can help security teams show that data leakage prevention is not just a written policy, but an operational capability.
Lunar turns DLP from a perimeter control into an exposure management program
The biggest mistake organizations make is assuming that DLP ends at the network edge. In reality, data leakage prevention now needs to account for the full exposure lifecycle: how sensitive access data is stolen, where it is traded, how quickly attackers can weaponize it, and how fast defenders can respond.
Lunar helps organizations expand DLP from a perimeter-focused control into a broader exposure management program. It provides visibility into compromised credentials, session cookies, tokens, and other access artifacts that may already be circulating across external threat environments.
For companies aligning with ISO 27002, Lunar supports a simple principle:
You cannot prevent the misuse of leaked data you cannot see.
By giving organizations visibility into exposed credentials, tokens, cookies, and related risk signals, Lunar helps security teams detect leakage earlier, prioritize the most dangerous exposures, and trigger remediation before stolen access becomes a full breach.
In ISO 27002 terms, Lunar strengthens detection, supports prevention, improves incident response, and helps organizations demonstrate that they are actively managing the risk of unauthorized data disclosure.
Explore Lunar to see whether your organization’s credentials, tokens, or exposed assets are already circulating across the deep, dark, and open web, and start turning external exposure intelligence into a stronger ISO 27002-aligned data leakage prevention program.
