Firewall Management Services
Depending on an organization’s security policies and the complexity of its data storage, network segments and other factors, the most common appliance – a firewall – often serves as the first defense against external cybersecurity threats.

Businesses and organizations of every size and industry must recognize the real and imminent threat of cybersecurity attacks. While many of the notable attacks are directed at enterprises and other organizations with large networks, SMBs are just as vulnerable because their networks contain reams of personal, highly valuable data that cybercriminals want to steal. In many cases, small to medium-sized businesses are even more vulnerable because business owners and key stakeholders often believe their organizations aren’t big enough to become the target of a cyberattack.
Many businesses have taken steps to secure their networks using a variety of software applications or hardware appliances designed to monitor, control and prevent malware spread or a network breach. Depending on an organization’s security policies and the complexity of its data storage, network segments, and other factors, the most common appliance – a firewall – often serves as the first defense against external cybersecurity threats.
What Firewalls Are & How they Work
An organization’s network security infrastructure may consist of traditional firewalls, next-generation firewalls (NGFWs), web application firewalls (WAFs), or operating system or third-party, software-based firewalls. These firewalls determine which network ports and protocols can be used for inbound or outbound network traffic. There are many types of firewalls, but the following are the most commonly used:
Packet-Filtering Firewalls: Packet-filtering firewalls control traffic at the protocol, port or IP address level. Unmonitored, cybercriminals can sneak into a network and spread malware. Furthermore, individuals within an organization may access data without permission. Packet-filtering firewalls help stop this from occurring.
Stateful Firewalls: A stateful firewall oversees all network connections and analyzes the type of traffic and data that attempts to enter the network. This provides meaningful insight into malicious traffic and critical lead time to ensure a mitigation process is in place in the event of a breach.
Next-Generation Firewalls (NGFWs): NGFWs provide the same protection as stateful firewalls and packet-filtering firewalls but include essential features such as Deep-Packet Inspection (DPI), Intrusion Detection Systems (IPS), anti-virus capabilities and website filtering.
The Challenge of Managing Firewalls
Given the dynamic nature of today’s enterprise networks, it’s not surprising that security teams are often in need of more robust and comprehensive management tools. Each application and service offers cybercriminals an opportunity to breach the network, compromise privacy and steal data. Organizations need firewall security that is flexible enough to handle various components and granular enough to take advantage of each firewall security solution’s intricacies and nuances.
Despite the advances in firewall features and capabilities, there are shortcomings and gaps that cybercriminals can exploit. The problem chiefly lies with the fact that security teams must deploy firewall appliances across various virtual and physical sites. When an organization has numerous sites that must be protected, integrating firewalls and managing their usefulness is challenging to do at scale. Common shortcomings include:
- Reduced visibility occurs when appliances are tied to a single location; this limits the amount of data the firewall can inspect.
- Scalability is an issue as well, as many firewalls possess a limited capacity to run their resources properly – this can lead to inspection jams, performance sacrifice and the need to deploy additional appliances.
- Additional appliances require additional time to manage, and the numerous installations, configurations, patches, upgrades and integrations can drag an IT team’s time.
- Not securing the firewall management console
- Not performing a firewalls rules audit periodically to determine if any security problems are imbedded in the rules set
- Not performing security updates in the firewalls firmware or operating system
InfoSystems can help.
InfoSystems brings in-depth knowledge, experience and partnerships to our firewall management engagements, thereby maximizing your investment and ensuring your network stays secure. We enlist a host of partners and software products to stay in front of these challenges and preserve our customers’ network safety. Our partners include:
In our digital world, organizations large and small face many challenges to network security, and analysts regularly discover new vulnerabilities. Your network must have the right solutions in the right place at the right time to mitigate these threats. InfoSystems provides the security expertise needed to confidently protect your environment’s vital resources, data and privacy.
When an incident occurs, it is imperative to be ready to handle the situation as quickly and efficiently as possible. Identification, containment and eradication are key to re-establishing normal operational levels. InfoSystems’ Incident Response Program (IRP) services provide your organization with cyber experts that can assist your IT team when dealing with the unexpected.
While current circumstances demand IT teams and security providers develop nuanced and far-reaching protocols to monitor these devices, mobile usage itself is not new, and there are capable means already in place through Mobile Device Management (MDM) that work to monitor, control, and combat network breaches.
The NIST (National Institute of Standards and Technology) Security Controls were instituted to support information systems’ ability to stay secure and resilient amid evolving threats and work to maintain the confidentiality, integrity and overall security of federal and industry information systems.
As cybercriminals become more sophisticated, it is imperative that enterprises and their security teams rise to the challenge and employ strong and comprehensive measures to protect network data. Penetration testing is one of the most effective ways to be proactive and aware of vulnerabilities and protocol.
SOC 2 is a technical audit that requires organizations to adhere to information security policies and procedures. Most specifically, SOC 2 focuses on technology-based service organizations whose business stores customer data in the cloud or service organizations that have technology-based access to customer data through managed service agreements.
