Elisa’s Anti-Scam Tech: A Finnish Blueprint for a Safer Europe

HELSINKI, FINLAND – November 26, 2025 – While consumers and regulators across Europe grapple with an unrelenting wave of fraudulent phone calls, Finland has quietly achieved a landmark victory. The nation has effectively neutralized a primary tool of digital criminals, turning the country into an unprofitable wasteland for phone scammers. This strategic success is not the result of a chance development but a targeted innovation by telecom market leader Elisa, whose patented technology now stands as a powerful, proven blueprint for the rest of the continent.

This month, Elisa’s solution was granted a European patent, a significant move that transforms a national security achievement into a valuable, scalable asset. The timing coincides with the innovation’s nomination for the prestigious European Crime Prevention Award and an endorsement from Europol, which highlights the Finnish model as a case study in effective cybercrime prevention. For investors and industry leaders, the message is clear: the playbook for defeating a problem that siphons an estimated €850 million from victims worldwide has been written, and a Finnish telecom holds the pen.

The Finnish Firewall

The core of the problem has been caller ID “spoofing,” a technique where criminals disguise their phone number, often impersonating a local or trusted entity like a bank or government agency, to deceive their victims. This method has been the linchpin of so-called “technical support scams” and other fraudulent schemes that have plagued consumers for years.

In 2021, Elisa developed and deployed what it calls the world's first technical method to identify and block these spoofed calls in real-time. The solution performs network-level analysis, detecting when a call originating from outside Finland purports to be from a Finnish number. The system flags this discrepancy and blocks the fraudulent call before it ever reaches the customer’s phone. The impact was immediate and profound.

"Our employees developed the solution themselves, and we deployed it in our network back in 2021," notes Karri Jäkkö, Director of Elisa's Cybersecurity and Service Management Center. "Criminals' profits in Finland have dropped from €7 million a year to just a few thousand, meaning Elisa's actions have already made Finland an unprofitable target for criminals."

Recognizing the public good, the Finnish Transport and Communications Agency (Traficom) took a decisive regulatory step. In 2023, it mandated that a solution based on Elisa's innovation be implemented by all telecom operators nationwide. This created a unified, digital iron curtain against spoofed calls. Since 2021, Elisa alone has blocked nearly 26 million scam calls, and the nationwide effort has virtually eliminated an entire category of fraud from the country.

A Strategic Blueprint for Europe

While Finland celebrates its success, the rest of Europe continues to bleed cash. In the United Kingdom, for instance, regulator Ofcom reported that consumers lost approximately £160 million to telecoms-enabled scams in 2024. These figures, which only represent a fraction of the broader fraud landscape, underscore the immense economic and social cost of inaction. They also highlight the significant market opportunity for an effective, scalable solution.

Elisa’s newly awarded European patent is a critical strategic development. It protects the company's intellectual property and positions the technology as a licensable solution for other operators across the continent. Europol has already called for unified technical standards and closer cross-border cooperation, and the Finnish model provides a ready-made, field-tested answer. Foreign operators are reportedly taking a keen interest, recognizing that adopting a proven system is far more efficient than attempting to reinvent it.

This strategic positioning is what elevates Elisa from a regional telecom operator to a potential leader in European cybersecurity infrastructure. The patent represents not just a technical achievement but a strategic investment in a solution that addresses a multi-hundred-million-euro problem. For investors, this demonstrates a capacity for high-impact R&D that can be monetized internationally, creating a new revenue stream and cementing the company's reputation as a technology pioneer.

The Ongoing Arms Race

Elisa’s leadership understands that victory in cybersecurity is never final. The fight against fraud is a dynamic “arms race,” requiring continuous innovation to stay ahead of adaptable criminal enterprises. The company’s strategy reflects this reality, extending far beyond its flagship anti-spoofing technology.

The company’s timeline of security innovations reveals a long-term commitment to digital protection. As early as 2020, Elisa was tackling “wangiri” scams, where fraudsters use missed calls to trick victims into calling back premium-rate numbers. In 2024, it partnered with Traficom to address fraudulent SMS messages by creating a system to block texts that falsely claim to be from registered organizations, such as the Finnish Tax Administration.

More recently, in 2025, Elisa began rolling out default security features for consumer mobile subscriptions, including malicious website blocking and data breach monitoring. In a particularly empowering move for consumers, it introduced an option for users to completely block all incoming calls from abroad—a blunt but effective tool for those who rarely expect international contact. These layers of defense demonstrate a comprehensive strategy focused on protecting the end-user at multiple points of vulnerability. This proactive, multi-front approach to security is what truly defines a leader in the digital age, showing an understanding that today's solution is merely the foundation for tomorrow's defense.
