What is a managed service provider?
A managed service provider takes ongoing responsibility for some or all of an organization's IT, including monitoring, patching, backups, help desk support and security. Instead of paying for each repair, clients pay a predictable fee, which helps small businesses budget and avoid surprise outages.
Do I need a security clearance to work for these companies?
Many roles on defense and intelligence programs require a clearance, but plenty of positions in commercial work, civilian agencies and corporate functions do not. Some employers sponsor clearances for qualified candidates, which can be a major career advantage in Northern Virginia.
How quickly should an IT provider respond to problems?
Response times should be defined in a service level agreement. Critical outages typically warrant a response within an hour, while routine requests may be handled within a business day.
