MDR for Claude: Securing Enterprise AI with Managed Detection and Response

Organizations are rapidly adopting generative AI platforms to improve productivity, accelerate innovation, and increase operational efficiency. Like many enterprise security providers, Proficio has embraced AI across the organization, from Security Operations Center (SOC) workflows and Detection Engineering to a growing number of specialized business use cases.

However, as AI adoption expands, so does the attack surface. Organizations using Anthropic’s Claude or internally developed large language models (LLMs) must understand and manage the security risks introduced by these technologies. AI has quickly become another critical business application that requires the same level of visibility, monitoring, and protection as any other enterprise system.

To address this challenge, Proficio has evolved its MDR for Claude capabilities to help organizations securely adopt and operate Anthropic’s Claude platform. Leveraging Claude Enterprise logging and Proficio’s Agentic AI SOC expertise, MDR for Claude provides the monitoring, threat detection, and response capabilities needed to identify AI-specific threats before they impact the business.

What Is MDR for Claude?

MDR for Claude is a managed detection and response service designed to monitor, detect, investigate, and respond to threats targeting Anthropic’s Claude AI environment. By analyzing Claude Enterprise telemetry and correlating activity with broader security data sources, MDR for Claude helps organizations identify malicious activity, risky user behavior, identity-based attacks, prompt injection attempts, and sensitive data exposure.

As AI becomes embedded in business operations, traditional security monitoring alone is no longer sufficient. Organizations need purpose-built visibility into how employees, administrators, and attackers interact with AI systems. MDR for Claude extends security operations into this new environment while supporting continuous cyber resilience.

Through our own AI adoption journey, Proficio identified three primary areas of risk associated with enterprise AI deployments:

• Prompt injection attacks
• Access and identity risks
• Sensitive data exposure

Using Claude Enterprise logging as a foundation, Proficio developed detection content and monitoring use cases specifically designed to address these emerging threats.

MDR for Claude: Detecting Prompt Injection Attacks

Prompt injection remains one of the most significant risks facing organizations using AI platforms. Attackers may attempt to manipulate the model’s behavior, bypass safeguards, extract restricted information, or influence future outputs through carefully crafted prompts.

If successful, these attacks can undermine the effectiveness and trustworthiness of AI systems across the organization.

Common prompt injection activities include:

• Repeated attempts to override instructions using phrases like “ignore previous instructions”
• Attempts to access hidden system prompts
• Tool abuse when Claude is connected to internal systems
• High volumes of blocked or refused prompts
• Rapid prompt iteration indicating automated experimentation

Proficio’s MDR for Claude monitors for these patterns and other indicators of potentially malicious activity.

Multiple Rejected Prompts from the Same User

Repeated prompt rejections may indicate that a user is persistently attempting to bypass Claude’s safeguards. While some activity may be legitimate experimentation, repeated failures followed by prompt refinement can suggest malicious intent.

MDR for Claude identifies these patterns and provides analysts with the context required to distinguish normal usage from potentially dangerous behavior.

Spikes in AI Safety Policy Violations

Commercial AI platforms such as Claude contain built-in safety mechanisms designed to identify suspicious requests and policy violations.

Proficio’s MDR for Claude monitors these events and correlates them with additional user and organizational context to determine whether activity represents a genuine threat or an isolated user error.

Prompts Containing Known Jailbreak Indicators

Threat actors often rely on known jailbreak techniques and commonly used phrases to manipulate AI systems.

Examples include:

• ignore previous instructions
• system prompt
• developer mode
• admin mode
• execute
• jailbreak
• tool calls

Individually, these phrases may appear in legitimate conversations. However, when evaluated together with user behavior, frequency, timing, and historical activity patterns, they can provide strong indicators of malicious intent.

Sequential Refinement After Refusals

Context is critical in security operations.

A single refused prompt is unlikely to represent a threat. However, a user who repeatedly modifies and resubmits prompts after multiple refusals may be testing the boundaries of Claude’s protections.

MDR for Claude applies behavioral analysis and contextual investigation to determine whether this activity represents routine usage or a deliberate attempt to exploit the AI environment.

Multiple Users Attempting Similar Exploits

Attackers frequently distribute activity across multiple compromised accounts to reduce detection risk.

Proficio’s MDR for Claude extends visibility beyond individual users and identifies coordinated activity patterns across multiple accounts. This broader perspective helps uncover attacks that may otherwise appear benign when viewed in isolation.

MDR for Claude: Monitoring Access and Identity Risks

For organizations that have adopted Claude Enterprise, AI has become another business-critical application that requires strong Identity and Access Management (IAM) controls.

Authentication, authorization, privileged access, and API usage must be continuously monitored to reduce the risk of account compromise or insider misuse.

Proficio’s MDR for Claude monitors for:

• New Claude users
• Privilege escalations
• API key creation
• API key abuse
• Login anomalies
• Impossible travel events
• Multifactor authentication failures
• Service accounts with excessive permissions

Claude API Usage from Unexpected Geographies

Geolocation remains an important indicator of suspicious account behavior.

If privileged users authenticate from unexpected locations and subsequently generate API keys or perform administrative actions, organizations may be facing a compromised account scenario.

MDR for Claude monitors these activities and applies organizational context to identify genuinely risky behavior.

Sudden Increases in API Activity

In most organizations, only specific users or applications should leverage Claude APIs extensively.

A sudden increase in API usage from accounts that do not normally perform these activities may indicate credential compromise, abuse, or unauthorized automation.

Proficio’s MDR for Claude analyzes user roles, historical behavior, and activity baselines to identify unusual API consumption patterns.

Administrative Changes

Many organizations are still early in their AI security maturity journey. As a result, governance processes that already exist for other business applications are often not fully applied to AI platforms.

Administrative actions such as adding users, assigning privileges, modifying permissions, or creating service accounts should be monitored with the same rigor applied to traditional enterprise systems.

MDR for Claude helps organizations detect suspicious administrative activity before it creates opportunities for threat actors to expand access within the environment.

MDR for Claude: Preventing Sensitive Data Exposure

One of the most important use cases for MDR for Claude is identifying situations where users may be exposing sensitive information to AI systems.

Organizations routinely process:

• Personally Identifiable Information (PII)
• Protected Health Information (PHI)
• Intellectual Property
• Source code
• Internal business documents
• Financial records

Without appropriate monitoring and governance, this information could be unintentionally shared or accessed by unauthorized users.

Examples of data exposure scenarios monitored by Proficio include:

• API keys
• PII and PHI
• Internal documentation
• Source code
• Business-sensitive project information

Leveraging Existing Security Investments

Proficio’s approach focuses on maximizing customer investments in existing security tools.

Organizations utilizing technologies such as:

• Data Loss Prevention (DLP)
• Cloud Access Security Brokers (CASB)
• Identity platforms
• SIEM solutions

can enhance the effectiveness of MDR for Claude through integrated visibility and contextual analysis.

Sensitive Data Monitoring Use Cases

Examples include:

• Large file uploads into Claude
• HR documents submitted to Claude prompts
• Finance records shared during AI interactions
• Source code repositories accessed immediately before AI conversations
• Excessive references to sensitive projects or confidential initiatives
• Unusual discussion volumes involving regulated data

By correlating Claude activity with DLP classifications, file metadata, and broader security telemetry, MDR for Claude helps organizations identify potential data leakage incidents before they escalate into significant business risks.

Why Organizations Need MDR for Claude

As enterprise AI adoption accelerates, threat actors are increasingly targeting AI systems as a new attack vector.

Traditional MDR services are designed to monitor endpoints, networks, cloud infrastructure, and identities. While these capabilities remain essential, they do not provide visibility into AI-specific attack paths.

MDR for Claude fills that gap by monitoring AI interactions, identifying emerging threats, and extending detection and response capabilities into generative AI environments.

Organizations that deploy Claude without appropriate monitoring may face challenges including:

• Prompt injection attacks
• Unauthorized access
• Credential compromise
• API abuse
• Insider threats
• Data leakage
• Compliance violations

Implementing MDR for Claude helps ensure that the benefits of AI innovation are not overshadowed by unmanaged security risks.
