 Meet Our Leadership

Cyberleaf's Mission

At Cyberleaf, we strive to democratize cybersecurity, bringing top tier protection to small and medium enterprises. We enable you to protect your vital systems and information via our comprehensive, economical approach to managed cyber protection.

In a crowded cybersecurity sector, we want our clients to feel empowered by knowing that they are appreciated, completely protected, and not paying more than is needed- leaving the opportunity for resources to be put toward the success of their business. 

Company Values

Honesty 

The existence of cyber threats is undeniable and growing. We accept reality as it is, not as we want it to be. Often other cybersecurity services charge too much, while not providing complete protection. Why spend excessive amounts of money on a fancy new door lock system, while leaving the window open? We candidly explain what is needed to secure the business, without the inflated prices.

Passion

We recognize the value of those who do what they love and bring it to the world. Let us help you protect what you're working so hard to build.

Work/Life Balance

Baba Ram Dass said, “Be here, now.” There’s no need to worry about the safety of your data and assets while trying to do a job- or even worse, when taking important time off. We want you to take the protection of your business into your own hands, by allowing us to do the work for you.
