Credit cards, social security numbers, social media logins and medical records all have immense value on the dark web. That’s why cybersecurity attacks are so costly and dangerous. In fact, it usually takes a company about 196 days to even discover that they were breached and potentially millions of dollars to fix the damage. But the real damage lies far beyond financial figures. In those six-plus months of going undetected, cyber criminals steal countless identities, company secrets, private health records and anything else of value, leading to immeasurable consequences for both company and consumer. 

Luckily, San Francisco cybersecurity companies are here to put our minds at ease. The Bay Area, as one of the world’s foremost security hubs, is working on outsmarting cybercriminals through advanced tech, like multi-factor authentication, malicious bot scanning software and post-perimeter monitoring to prevent attacks before they can even happen.
