Stopping Vishing Scammers

Learn how Teknosa turned the tide on an ongoing voice phishing risk across 211 retail locations, with a potential $439,250 annual loss!

How Teknosa Fought Voice Phishing with Keepnet


Teknosa, a leading technology retailer, employs around 2,500 staff and operates 211 stores across 68 locations, with a strong online presence.

Their customer-focused approach depends on providing excellent sales and support services over the phone. However, phone scams exploiting customer trust have caused problems, lowering employee morale, wasting customer service time, and leading to financial and legal issues.

To address this issue, it was significant for all employees, from customer representatives to sales managers, to learn how to identify and report these scams. An automated, sustainable, and swift solution was necessary. Keepnet’s Vishing Simulator was the ideal choice 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."
