Firewalls & Keeping Your Business Files Safe
Types of Firewalls
Firewalls can either be physical or logical. A logical firewall is usually found built into an operating system and is typically controlled by a server within a business environment. The configuration of a logical firewall requires a certain level of technical expertise to regularly maintain & tweak settings to help the firewall work correctly.
A physical firewall is a network device that is usually used as the first point of entry for traffic entering a network. It applies intense scrutiny to the traffic, checking for unwanted intrusions and viruses before the traffic is allowed to end-point device, such as a Windows server, employee computer, or any mobile device. Many physical firewalls offer subscription-based services that may be necessary for compliance reasons and overall security of the network. Subscription based firewalls are updated multiple times a day with threat lists from subscribed security experts, sources, and companies.
Choosing the Best Firewall for your Business
TechStarters will help you choose the right firewall for your business, here are the main considerations we take into account when choosing an appropriate firewall for a business environment:
- Cost of Ownership
- Manageability & Reporting
Scale defines the size and shape of your environment. A few of the scale questions we ask to help determine the best Firewall solution for your business: How many employees access the network? Does the organization have multiple sites? How many remote users? Scale is just one item that ultimately determines the firewall level of product you will require.
Security defines the strength of protection provided by the firewall device. What is the information that your company deals with internally and externally. Do you use online financial services or handle medical information? Must your company stay PCI or HIPAA compliant? At minimum, most devices provide a straight forward form of protection with the ability to configure higher levels of firewall protection, usually under an optional form of paid subscriptions.
Cost of Ownership
Cost of ownership defines the bottom-line of cost to you, from start to finish, including (but not limited to) purchase or lease of hardware, configuration and installation, service subscription, and maintenance.
Manageability & Reporting
Ease of management can impact your cost of service over time. Some devices are very simple and easy to make administrative changes, while the majority of other firewalls are far more complex and require a high-level IT professional to have specialized training in order to manage the firewall properly.
To one degree or another, reporting is a feature necessary feature built into most commercial firewall devices. Some reporting platforms are very simplistic in the information gathered, while the more sophisticated firewalls provide much more granular reporting features.
