From Detection to Containment: A Practical Deepfake Response Playbook

Alex Lisle

CTO

Deepfakes are now being used to bypass controls and access to data inside organizations. Security teams are encountering AI-generated or manipulated audio and video during password resets, access recovery, hiring, and executive communications.

These incidents expose a growing gap in many security programs. Most processes still assume that seeing or hearing someone provides assurance they’re real. Deepfakes break that assumption, turning trust-based channels into attack paths.

This playbook is written for security teams. It explains how deepfake threats have evolved, why traditional trust models fail, and how organizations can move from ad hoc reactions to structured detection, response, and containment.

Deepfakes Have Moved Into the Cybersecurity Kill Chain

Early deepfake activity focused on direct financial theft. Attackers impersonated senior executives, such as chief financial officers or chief executive officers, to authorize payments or extract sensitive information.

That model has expanded. Modern deepfake attacks now serve multiple purposes within traditional cybersecurity attack vectors:

  • Account escalation - Bypassing authentication systems
  • Reconnaissance - Gathering intelligence through social engineering
  • East-west migration - Moving laterally through network systems
  • Trust boundary exploitation - Undermining verification processes

As a result, deepfakes no longer represent a single failure point. They now cut across identity, access, and communications controls, creating risk that spans both technical systems and human decision-making.

How Deepfakes Exploit Everyday Communications

Many identity recovery and exception workflows are built on a simple assumption: if you can see and hear someone, you can trust who they are.

Consider a typical scenario. An employee fails a password reset or biometric check and the issue escalates to a manager for visual confirmation over a video call. The manager is asked a straightforward question: Is this the person who works for you? For years, that step provided sufficient assurance to restore access.

That same process now introduces risk. The individual on the screen may not be the employee at all, but a convincing AI-generated impersonation. What was designed as a safeguard becomes an entry point, not because the process failed, but because the trust model behind it no longer holds.

These verification steps sit outside traditional technical controls and rely on human judgment rather than enforcement. As deepfakes become more accessible, organizations must reassess where visual or audio confirmation is still acceptable and where additional verification is required.

Where Deepfake Detection Needs to Live

Effective deepfake controls require coverage across multiple operational environments. Risk does not sit in a single system or channel, and detection strategies should reflect how media moves through the organization.

Protect the Environments Where Trust Is Exercised

Organizations typically need to account for three distinct environments, each with different risk profiles. 

1. Production Environment

Customer-facing production systems are typically the most mature from a security perspective. They are tightly controlled, monitored, and tested because they support live products and services. These environments often already use automated detection and abuse prevention at scale. While the reputational and financial stakes are high, the attack surface is usually well understood and comparatively well defended.

2. Internal Infrastructure

Internal infrastructure represents a very different risk profile. Employee laptops, mobile devices, collaboration tools, and internal communications form a broad and often unevenly protected attack surface. These systems sit outside the core production stack but frequently serve as gateways into it.

This environment also places humans directly in the loop. Identity verification, access recovery, approvals, and exception handling often rely on judgment rather than enforcement. As a result, internal infrastructure remains one of the most effective entry points for social engineering and deepfake-enabled attacks, precisely because controls are informal and trust-based.

3. Contact Centers and Service Operations

Contact centers introduce a third category that many security teams historically treated as a fraud issue rather than a cybersecurity concern. These environments combine real-time interaction, identity verification, and account or financial authority. Decisions are made quickly, often under pressure, and frequently rely on voice or visual confirmation.

As agentic AI and deepfake-enabled impersonation increase, these environments now sit squarely at the intersection of fraud, identity, and security risk. They require controls that reflect how trust is exercised in live conversations, not just how systems are protected.

Deepfake prevention strategies should align to these environments to reduce exposure without adding unnecessary friction.

Determine Which Scenarios Require Priority Coverage

Not all interactions carry the same risk. Certain scenarios consistently justify enhanced monitoring due to their authority, reach, or downstream impact.

  • Executive communications often involve access to sensitive information or decision-making authority. Financial authorization workflows present direct monetary exposure. 
  • Technical discussions that reference credentials, system access, or configuration changes can enable broader compromise. 
  • Prepared statements or recorded presentations also deserve attention, as attackers can exploit predictable formats to generate convincing manipulated media.

Prioritizing these scenarios helps teams concentrate resources where deepfakes are most likely to cause harm.

Extend Detection Beyond Live Interactions

Deepfake risk does not end with real-time voice or video. Organizations increasingly encounter manipulated media through shared files and stored content.

Detection should include: images, audio, and video received via email attachments, collaboration platforms such as Slack or Microsoft Teams, and other internal file-sharing channels. Any point where employees consume or act on media content represents a potential trust boundary.

Equally important is awareness. Teams should understand when content is AI-generated or manipulated, even when intent appears benign. Clear visibility reduces the risk of unintentional amplification, misinterpretation, or downstream misuse.

Building a Deepfake Response Playbook

An effective response to deepfake incidents starts with accepting a basic reality. Detection alone is not enough. Organizations need clear, repeatable actions that teams can follow when manipulated audio or video appears in live workflows.

The goal of a deepfake response playbook is operational control. It should help teams act quickly, preserve evidence, and limit downstream impact without overreacting or relying on ad hoc judgment. Here are the steps to follow: 

1. Integrate Real-Time Detection Into Core Security Systems

  • Deploy detection APIs across all communication channels
  • Feed signals to your SIEM for centralized monitoring
  • Connect to your SOC for immediate analyst response

Detection works best when it fits into existing security operations rather than sitting in isolation. Organizations should integrate deepfake detection into the same infrastructure they use to monitor other forms of risk.

Detection signals should be fed directly from communication channels into centralized monitoring systems, such as a Security Information and Event Management (SIEM) platform. From there, alerts should flow directly to the security operations center (SOC) so analysts can assess and respond in real time.

From an operational standpoint, early visibility matters more than perfect certainty. A timely signal allows teams to slow down decisions, introduce verification steps, and prevent trust-based escalation.

2. Define Immediate Response Protocols for Live Incidents

When deepfake detection triggers, your response must be swift and systematic:

Priority 1: Preserve Evidence

When detection triggers during a live interaction, teams need clear guidance on what happens next. The first priority should always be evidence preservation. Recording the call or meeting ensures there is material for review, investigation, or regulatory reporting. Unlike many cyber events, deepfake incidents can disappear the moment an interaction ends.

Priority 2: Multi-Channel Notification

The next priority is notification. All participants should be informed that a potential manipulated interaction has been identified, and the incident response team should be alerted. Teams should avoid relying on a meeting host to respond to a deepfake signal, as that role itself could be compromised.

Priority 3: Implement Authentication Challenges

Finally, response playbooks should define authentication challenges that can be applied immediately. In lower-risk scenarios, use soft authentication: "I'll call you back on a verified number". In higher-risk situations, use hard authentication where teams may request additional credentials or secondary approval. These steps should reflect the organization’s risk tolerance and the sensitivity of the interaction.

3. Use Risk-Based Response Tiers to Guide Action

Not every deepfake alert warrants the same response. Mature programs define response tiers based on potential impact rather than treating every incident as a full breach. Your response should scale based on the potential impact:

Tier 1 - Minimal Response

This tier applies to low-risk interactions with no system access, financial authority, or sensitive data exchange, such as an early applicant interview

  • Record the interaction for review and pattern analysis.
  • Log the event for monitoring trends over time.

The objective is visibility, not disruption. These incidents help teams understand the scale of deepfake issues without interrupting normal operations.

Tier 2 - Active Notification

This tier applies to standard business communications where trust and decision-making are involved.

  • Notify participants that a potential deepfake has been detected.
  • Introduce additional verification before continuing the interaction.

At this level, the goal is to slow decision-making and reintroduce verification without immediately escalating to containment.

Tier 3 - Immediate Containment

This tier applies when the interaction involves elevated access, privileged accounts, or sensitive environments.

  • Terminate the communication.
  • Restrict or suspend affected accounts and access paths.
  • Reset credentials associated with the interaction.

These actions prevent further exposure while teams assess whether the incident reflects broader compromise.

Tier 4 - Full Breach Protocol

This tier applies to critical scenarios involving executives, financial authority, or systems tied to core operations.

  • Treat the incident as an active security event.
  • Isolate affected systems and environments.
  • Activate full incident response procedures.

At this level, the focus shifts from verification to containment and recovery, following the same rigor used for confirmed security breaches.

Preparing Security Teams for Deepfake Incidents

Effective preparation starts with integration. Teams should incorporate deepfake detection into existing communication systems and then feed those AI manipulation signals into security platforms, alongside controls for malware, phishing, and unauthorized access. This approach avoids creating parallel processes and supports a consistent response.

Organizations also need tiered response protocols that scale with risk. Clear thresholds help teams act quickly without overreacting. Training matters as well. Staff need to understand that visual and audio confirmation alone no longer provides reliable assurance, especially in trusted communication channels.

Finally, planning should account for scenarios where manipulated media appears in familiar workflows, such as internal meetings, customer interactions, or executive communications. These are often the hardest incidents to recognize and the most costly to mishandle.

Organizations that address deepfake risk now will be better positioned to maintain operational control as incidents increase. The focus is not only on protecting systems and data, but on preserving trust in digital communication where decisions are made.
