One Source Unlocks Fortune 500-Strength Cybersecurity for All

No matter the size of your company, threat actors use the same sophisticated techniques but unfortunately small to medium-sized organizations suffer more because they aren’t armed with the same defenses – until now.

One Source unlocks Fortune 500-strength cybersecurity for all. Our team of managed security experts protect you from risks – and their devastating consequences – by implementing a proactive, cohesive strategy specific to your industry, technology environment and vulnerabilities. And thanks to our longstanding partnership with FireEye, we have access to the highest level of cyber intelligence to fend off newly-revealed hackers and their means of attack.

Your company cannot rely on out-of-the-box tools and software alone. You need a Managed Security Operations Center (SOC) that has the skills to proactively defend your company from cyber threats.

Your company could be hacked at any moment.

Uncover Security Risks with a Free Threat Assessment

One Source’s Security Operations Centers

As a Managed Security Services Partner or MSSP, we have multiple SOCs or Security Operations Centers staffed by the industry’s top experts to provide in-house Managed Detection and Response (MDR). Unlike other cybersecurity solutions, we’re not an “alert cannon”. We don’t tell you when you have a security breach and leave it for you to handle – we remediate the issue for you, so you never have to worry about it.

Cybersecurity Shouldn't be a Siloed Approach

A siloed approach to cybersecurity will not provide the most comprehensive protection. Our end-to-end approach identifies threats and provides contextual reporting about your entire connectivity environment. And our tangential expertise in connectivity and IT infrastructure allows us to provide the best guidance and protection for your business, preventing cyberattacks on all fronts.
