Financial Rating Org Deploys SecureLogix and Prevents TDoS Attacks


An international financial credit rating organization is warned in advance of a coordinated TDoS Attack against the company’s contact centers. With help from SecureLogix and the Force Field solution they are able to not only withstand the attack, but to defeat it without so much as a single minute of communications downtime.

“With SecureLogix we were able to withstand a sophisticated TDoS attack without losing a single minute of contact center operations.”


An international financial credit rating organization discovered that there were plans to use social media to organize a flash-mob Telephony Denial of Service (TDoS) attack against its voice systems and services. The rating company had recently downgraded the credit rating of a country. A group of angered residents of this country used Facebook to organize a coordinated calling campaign against the rating company’s contact center in an attempt to suspend all voice services.


The ratings agency learned of the planned attack online, and contacted SecureLogix to learn how to best defend against the impending attack. SecureLogix completed a 24-hour turnaround deployment of its Force Field voice security solution to cover the New York City and London contact centers just hours before the attack.


Through a combination of TDoS calling pattern recognition, individual threatening call identification, and dynamic blacklist policy management, SecureLogix was able to alert and block calls associated with the attack. Meanwhile, the contact centers were able to receive and process all of their legitimate business calls and transactions. Post-event reporting showed that, without the deployment of SecureLogix® technology, the social networking TDoS attack would have successfully taken down all voice services in the target contact centers.
