“There is no substitute for proactive Security”

Much as you would love to believe that you are safe you are not. Chances are that a new Vulnerability was discovered a few weeks after you patched your servers. We can take the pain out of managing security for you through our Security centric services.

Bolstered by our vast experience in securing and resurrecting mission-critical servers and over 6 years of core system administration and impelmetation work, we provide you with a comprehensive-one stop server security solution.

Unlike those fancy “consultants”, who charge you a million bucks and leave you all scared and sweating, we have been in the field, grappled with real issues and patched real servers (not the ones in a lab or in a textbook). We have what it takes to make your servers “really” safe. We don’t just tell you what your problems are but we go the whole nine yards and “fix it” so you can sit back and relax.

Our services include but are not restricted to:

Security incident handling and emergency rescue operations.
framing of security policies, keeping in mind target systems/users
Basic and Advanced vulnerability Analysis of servers
Application Security Audits
Firewall implementation and tuning
Disaster Recovery and Redundancy planning
centralized as well as offline log repository management and monitoring
Mail and Messaging systems security

As stated earlier we do not restrict ourselves within the above stated activities. We take each case on a one to one basis and proceed to evaluate and suggest a solution that we can provide and that you would like to take from us. So please feel free to contact us.
