REAL-TIME RANSOMWARE CONTAINMENT PROTECTS CRITICAL FINANCIAL DATA
SUMMARY
A leading European financial firm serving over 5 million customers in the private, commercial, and corporate markets needed a cybersecurity solution to mitigate the rising threat of ransomware attacks. After their network of security solutions failed to protect them—costing critical downtime and millions of dollars—they turned to BullWall. Leveraging BullWall’s ransomware containment solution, the finance company quickly identified and neutralized security threats with minimal disruption to its operations. Over 5 years, the company has saved over $35 million using BullWall’s solution.
AN INDUSTRY HELD HOSTAGE
Ransomware is a growing threat to organizations around the world. The financial service industry has been hit particularly hard with a 35% rise in attacks quarter-over-quarter in 2022, including a 13% increase in ransomware attacks on insurers. Finance companies handle a significant amount of personally identifiable information (PII), making them ideal targets for ransomware attacks.1
Seeking to protect itself against these growing threats, one leading European financial service firm adopted a collection of preventative solutions. It implemented a robust security stack of Mimecast, Cisco, Symantec, and McAfee and hired a 24-hour IT Security Company to monitor their network environment for malicious cybercriminal activity manually. But when a ransomware attack occurred, the finance company was left scrambling to mitigate the damage.
THE HIGH COST OF INADEQUATE PROTECTION
Despite the company’s extensive security stack, ransomware could propagate undetected, and an active attack was discovered purely by coincidence. Security analysts were monitoring fileshare activity to review the number of active employees on a business application. During this routine review, the analysts inadvertently noticed malicious encryption activity taking place within the network.
Over the next four hours, 429,000 files were encrypted as IT personnel frantically rushed to unplug IT equipment to prevent further infrastructure damage. The breach caused 9 days of operational downtime and cost the company an estimated $8 million.
Seeing that their current security stack had failed to identify or prevent the ransomware attack, the company’s CISO knew they needed another layer to their security stack.
The company became aware of an innovative cybersecurity company, BullWall, which developed a ransomware containment solution. Unlike other solutions, which focus on ransomware prevention, BullWall detects and contains active ransomware attacks by monitoring the activity on file shares, cloud data storage, application servers, and database servers.
BullWall does not depend on outdated detection methods such as ransomware signatures, strains, patterns, or behavior. Instead, BullWall’s Ransomware Containment rapidly detects both known and unknown strains of ransomware by identifying malicious file activity. It does so without any network overhead or performance degradation. Later that year, BullWall was put to the test.
MONEY SAVED. TRUST EARNED.
During a routine update, the email compromise tools were offline for 19 minutes. In that short time, three employees opened malicious email attachments that began to encrypt data rapidly.
Within seconds, BullWall’s solution automatically isolated the three users by disconnecting them from Active Directory to prevent widespread damage. BullWall then alerted IT personnel, providing a list of all compromised users, devices, and data. This enabled the team to focus on restoring the network instead of manually investigating the incident, slashing their recovery time. Thanks to BullWall’s solution, the threat was contained before the IT Security Monitoring Provider had even detected the malicious activity.
As a result, all data and endpoints were fully restored and operational within 24 hours.
On average, companies hit with ransomware experience 24 days of operational downtime, costing $4.62M to recover. Since its installation, BullWall has saved the company an estimated $35.8 million, reduced downtime from days to hours, and given them peace of mind that their data is secure across the organization.
