Average handle time (AHT) is one of the most important metrics in the contact center. Lowering AHT improves efficiency and reduces operational costs–but reducing handle time should never come at the expense of service quality or security.
Every extra second spent authenticating a caller increases operational costs, frustrates account holders, and reduces agent efficiency. For many contact centers, traditional authentication processes remain one of the biggest hidden contributors to AHT and account holder frustration.
The organizations reducing AHT most effectively are not rushing callers off the phone–they are eliminating friction throughout the account holder journey. By streamlining authentication, reducing repetitive verification, and improving agent efficiency, contact centers lower handle time while strengthening both security and customer experience. The most effective way to maximize efficiency without compromising the experience is by eliminating friction throughout the account holder interaction.
Reducing AHT impacts more than just operational metrics. It directly influences:
Agent productivity
Staffing requirements
Hold times
Operational costs
Long handle times also increase account holder frustration–especially when the call is finally answered, and callers are forced to repeat information or answer multiple security questions.
Several common issues increase handle time in contact centers:
Lengthy authentication processes
Repetitive verification across channels
Manual agent workflows
Fraud investigations and escalations
Disconnected systems and tools
One of the biggest contributors is traditional knowledge-based authentication (KBA), where agents spend valuable time asking security questions before they can even begin helping the account holder.
Across large contact centers, reducing just seconds from each interaction can translate into significant annual savings while improving service quality and consistency.
Passive voice authentication allows organizations to verify callers naturally during conversation instead of relying on multiple security questions.
This dramatically reduces verification time while improving both security and account holder experience.
Account holders should not need to re-authenticate as they move between IVR systems, virtual assistants, and live agents. Maintaining authentication across channels eliminates unnecessary friction.
Providing agents with authentication status, fraud alerts, and account holder context in real time helps them resolve calls faster and more confidently.
Secure IVR and IVA systems can handle routine requests such as balance inquiries, payments, and account updates–reducing contact center call volume and allowing agents to focus on more complex interactions.
Reducing screen switching, manual data entry, and after-call work can save valuable time on every interaction.
IllumaSHIELD™ reduces the biggest drivers of high AHT and accountholder frustration by eliminating friction across authentication, fraud prevention, and customer interactions through:
Passive voice authentication reduces time spent on manual security questions, allowing agents to move directly into resolving the caller’s issue
Layered Voice Security maintains authentication across IVR, IVA, and live agent interactions, eliminating repetitive verification steps that increase handle time
Real-time fraud detection and deepfake risk scoring give agents immediate intelligence during higher-risk interactions, reducing escalations and investigation time to only when absolutely needed
Adaptive MFA applies additional verification only when risk is detected, reducing unnecessary friction for legitimate callers
Secure self-service authentication improves IVA and IVR containment, reducing live call volume for agents
Real-time caller intelligence provides agents with authentication status and risk insights faster, improving efficiency and confidence during interactions
Streamlined authentication and fraud prevention workflows help organizations reduce handle time while improving both security and customer experience
By verifying callers naturally during conversation, IllumaSHIELD helps organizations reduce authentication friction while strengthening fraud prevention.
Organizations using IllumaSHIELD have reported:
Up to 95% faster authentication
80+ second AHT reductions
Faster call resolution
Improved account holder experience
Because IllumaSHIELD is often implemented in days, organizations can modernize both security and efficiency quickly.
Reducing AHT is not about rushing account holders off the phone. It’s about removing unnecessary friction, improving workflows, and enabling agents to resolve interactions faster and more securely.
