Mobile App Reputation Service (MARS)

Uncover Hidden Risks in Your Mobile App Ecosystem

This is some text inside of a div block.

In a mobile-first world, employees often install third-party apps—sometimes from unofficial sources—on both personal and work devices. Lookout’s Mobile App Reputation Service helps organizations evaluate and monitor the behavior, privacy risks, and threat levels of mobile apps—both before and after they're installed on a device.

Automated analysis of every app in your environment.

Mobile apps are critical to productivity—but they can also introduce serious, often overlooked security risks. The Lookout Mobile App Reputation Service delivers deep, automated analysis of every app in your environment, enabling security teams to make informed allow/deny decisions based on actual risk—not guesswork.

Analyze app behavior

Identify apps that access sensitive data, perform risky actions (e.g., sending data to unknown servers), or exhibit suspicious behavior in the background.

Assess privacy risk

Flag apps that request excessive permissions, share data with third parties, or include embedded trackers or adware.

Detect known threat

Use threat intelligence to identify apps that are known to contain malware, spyware, or trojans

Score risk level

Assign a reputation score (e.g., low, medium, high risk) based on the app's behavior and metadata, helping organizations make informed decisions about which apps to allow.

Support compliance and policy enforcement

Enable security teams to block or restrict apps that violate corporate policies or regulatory requirements.

Make sense of mobile app risks.

We provide actionable insights into every app across your mobile fleet, enabling automated policy enforcement based on the specific risk each app poses to your organization. Our AI models are continuously trained on hundreds of millions of apps—with thousands more added every day—to deliver unmatched visibility. With Lookout, security teams can confidently manage app exposure and ensure only trusted apps are allowed

Automated metadata extraction.

We collect and analyze key metadata for every application—such as app authorship, digital signatures, and build history—to establish a detailed profile of its origin and evolution.

Code-level insight.

Unify your security operations by streaming mobile threat data into your existing tools. Extend web content filtering, threat intelligence, and access controls to mobile endpoints—ensuring policy alignment across your entire device fleet and supporting your acceptable use standards.

Real-time behavioral analysis.

Every app is executed in a secure, cloud-based emulator, allowing for real-time observation of its behavior. This includes monitoring data access patterns and outbound network connections to uncover suspicious activity.

Comparative ecosystem analysis.

We evaluate every app in the context of the broader mobile ecosystem. By identifying patterns and similarities to known threats, we can quickly detect malicious variants and outliers that deviate from normal behavior.

Actionable App Intelligence.

Through the Lookout console or API, administrators get real-time visibility into critical risk indicators, enabling informed decisions and automated enforcement:

App risk score

Severity ratings from low to critical based on behavior and threat potential.

Capabilities & permissions

Detailed insight into access to GPS, SMS, microphone, clipboard, and more.

Network behavior

Tracks destination IPs, unencrypted traffic, and geographic endpoints.

Known vulnerabilities

Flags associated CVEs and exploitable code paths.

OWASP top 10 compliance

Assesses adherence to industry best practices for mobile app security.

Third-party SDKs

Identifies embedded libraries that may introduce risk or compliance issues.

Spoofing indicators

Detects inconsistencies in developer info, certificates, or app branding.

Hands-on labs: Experience mobile app vetting in action.

Use case

Identify apps with hidden risks.

‍

Even trusted or popular apps can introduce hidden threats. Lookout automatically flags applications that:

‍

Request excessive or unnecessary permissions (e.g., camera, microphone, SMS)
Access or transmit personally identifiable information (PII) such as location, IMEI, or contacts
Contain unvetted or vulnerable third-party SDKs that increase exposure or create compliance issues
Communicate with high-risk or untrusted domains, including those linked to adversarial regions

‍

With granular risk insights, Lookout empowers security teams to take proactive measures—before threats ever reach users.

Use case

Enforce compliance.

‍

Organizations in regulated industries—like healthcare, finance, and government—must maintain tight control over mobile apps. Lookout helps ensure:

‍

Only apps that meet your data protection and compliance standards are permitted
Immediate visibility into apps that may violate GDPR, HIPAA, or industry-specific regulations
Continuous monitoring with alerts if an app's risk status changes due to new behaviors, vulnerabilities, or updates

‍

With Lookout, you maintain audit-ready oversight and complete control across your entire mobile app environment.

Use case

Detect spoofed or malicious apps.

‍

Attackers often disguise malware as legitimate apps to bypass defenses and trick users. Lookout detects these deceptive apps using:

‍

Metadata analysis to identify mismatched developer credentials, altered certificates, and logo inconsistencies
App Genome Sequencing to compare app code against known malware and uncover lookalike variants
Behavioral analysis to detect hidden threats, including dormant malware, code injection, and data exfiltration

‍

With Lookout, security teams can confidently block tampered or spoofed apps—before they reach users or compromise sensitive data.
