Silencing Vishing Scammers

How Teknosa Turned the Tide on an Ongoing Voice Phishing Risk Across 211 Retail Locations, with a Potential $439,250 Annual Loss!

Case Study Icon


Teknosa is a leading technology retail network with a workforce of approximately 2,500 employees, operating a chain of 211 retail stores spread across 68 different locations. In addition to their physical stores, they have a strong online presence, with a well-established website facilitating a substantial portion of their sales.

Their customer-centric business model relies heavily on providing top-notch sales and support services via telephone. Despite their dedication to customer satisfaction, the company has been challenged by the problem of phone scams aimed at exploiting the trust between customers and employees.

These fraudulent activities not only undermined employee morale and motivation, but also stole precious time from customer service, leading to considerable financial losses and potential legal repercussions.

In an effort to address these threats effectively, all employees, from customer representatives to sales managers in their 211 retail stores across 68 locations, had to understand, resist, and report such attacks. An automated, sustainable, and swift solution was required. Keepnet’s Vishing Simulator emerged as the perfect fit for these needs.

Successful Outcomes

  • The annual ROI was $30,000
  • $439,250 of potential financial loss was prevented annually
  • Employees were 80% better at recognizing fake phone calls in the first 90 days

Impact of Vishing Attacks

Without a systematic approach to preventing phone scams, Teknosa would indeed be exposed to a range of risks. These could include:

  • Penalties and legal actions: Legal obligations mandate employee training against all cybersecurity risks, including vishing attacks. Non-compliance can result in financial penalties and legal actions.
  • Financial Losses: Successful vishing attacks can result in customer data leaks and potential ransom demands. There are also costs associated with incident response and mitigation.
  • Reputation Damage: Loss of trust among customers and employees could have devastating short-term and long-term consequences.
  • Business disruption: Suspicious activities or real attacks can divert significant attention, disrupting business operations.
  • Identity theft and fraud: Personal information gathered through voice phishing can lead to identity theft and associated fraudulent activities.

"Keepnet’s Vishing Simulator helped us craft scenarios tailored to our culture and goals, enabling our employees to identify, report, and counter cyber-attacks coming from phone. Keepnet contributed to a 30% increase in business efficiency, and our ability to identify and stop risks increased 12-times more."
