In the age of the digital economy, traditional brick and mortar banks are giving way to a new breed of online-only financial institutions. The task at hand for these fully digitized financial institutions is not easy: they need to deliver a smooth, secure, and flexible experience to their customers all over the world.
With the ever-increasing threat and sophistication of cyber attacks, the emphasis on security has become paramount for these new-age financial institutions. Any breach of security can drastically impact their business and unnerve customers.
SoFi, based out of San Francisco, is a well-known name in the world of online-first financial institutions. Started in 2011, they have revolutionized the way people borrow, spend, earn, and invest money. They have over 800,000 members and have funded over $40 billion in loans.
Facing a constant threat from cyber attacks, SoFi’s security team started looking for a Web Application Firewall (WAF) in 2018. They wanted an easy-to-use solution that not only blocked nefarious traffic but also became intelligent over time as new threats emerged. In the beginning, they tried some of the WAF solutions that their cloud providers offered; however, none of them were up to the task. Some lacked comprehensive features and rulesets, while others required a great deal of engineering effort to set up and maintain.
The Cloudflare Solution
Cloudflare emerged as the answer SoFi was looking for — an easy-to-use WAF solution that offers comprehensive rulesets to stop emerging and sophisticated threats. Cloudflare’s network across 25 million internet properties acts as an immune system for the internet — learning from any attack on one property to better protect them all. With Cloudflare, SoFi is constantly protected against any new vulnerabilities that crop up on the Internet.
Using Cloudflare WAF, SoFi’s engineers took almost no time to build and deploy granular rule sets and were able to reduce malicious traffic by over 60%, with a significantly low false-positive rate.
SoFi was also able to add an additional layer of authentication for its international visitors by leveraging Cloudflare Workers, Cloudflare’s serverless development platform. Deploying a mobile validation solution at the network edge using Cloudflare Workers enabled SoFi to filter out malicious traffic that was spoofing their real users — without any compromise to performance.
• SoFi was able to reduce malicious traffic by over 60%, with a significantly low false-positive rate.
• Using Cloudflare WAF's comprehensive rulesets, SoFi is constantly protected against any new vulnerabilities that crop up on the Internet.
「Cloudflare WAF was so easy and intuitive to use. It took our engineers almost no time to get up to speed. We’ve now expanded our usage of Cloudflare’s suite of products. Integrating with any Cloudflare solution has been just so smooth and painless.」
