Is Your Cybersecurity Advanced Enough To Keep You Secure?

Most organizations have security tools in place. What they often lack is the engineering depth to know whether those tools are actually configured correctly, covering the right things, and holding up over time.

HNI brings the firewall and security engineering experience to close that gap, working in Cisco and Palo Alto environments where precision is not optional.

Stress Free Experience

“Our wireless network could not reach all of our office rooms. We reached out to HNI Consulting and they sent a technician named Courtney and she was simply amazing! Courtney explained WiFi in a way that we never understood. She did a survey of our current wireless coverage and explained how much equipment we would need in order to reach our demand. Soon after the equipment was installed and we haven’t had to revisit the issue at all. The experience was very stress free.”

Excellent Customer Service

“Amazing service. Thank you! Our company agreed to work with HNI Consulting for our business/networking needs. Their customer service from the start was superb. They gave us a consultation, explained everything in a way we can understand, gave us product suggestions, and installed the computer equipment extremely efficiently. HNI was able to consult the company on our security risk and offered ongoing support for our network as well.”

How HNI Engineers Your Security Environment

Strong security does not come from buying the right tools. It comes from understanding how your environment is actually built, knowing where the real gaps are, and making sure every layer of protection is configured to do what it is supposed to do.

Environment Assessment

HNI security engagements start with understanding your environment before making recommendations. We need to know how your network is built and where the real exposure sits before we suggest anything.

Firewall Engineering Work

HNI designs and implements firewall architecture in Cisco and Palo Alto environments with the precision production networks require. Rule sets are built to reflect how traffic moves through your IT.

Security Policy Design

Good firewall policy reflects how your organization actually operates. We build rule sets around your real traffic patterns and access requirements, not a generic template that gets adjusted over time.

Ongoing Security Management

Security posture drifts without consistent attention. We manage policy, actively monitor for configuration changes, and review firewall rule sets on a regular cadence to make sure you're secure.

Why Your IT Needs Clarity

If your IT feels unpredictable, scattered, or reactive, it’s likely costing you more than just time. Without structured, insight-based support, even small issues can spiral into costly disruptions that limit productivity and create long-term operational risks.

Our managed IT services are designed to replace uncertainty with expert clarity. By aligning your systems with proven best practices and strategic foresight, we help your business run more efficiently, reduce unnecessary costs, and prevent problems before they arise.

Clients choose us because we’re consistent, accountable, and focused on outcomes that matter. From planning to execution, every piece of your IT environment is managed with care, precision, and a level of detail that transforms how technology supports your success.

Firewall Engineering

Design and Implementation for Cisco and Palo Alto Platforms

Firewall engineering is core to what HNI does. We design, implement, and manage firewall infrastructure in Cisco and Palo Alto environments, building rule sets and architecture around how your network actually operates. That means understanding your traffic patterns, your segmentation requirements, and the specific threats your environment faces before touching configuration. The goal is not a firewall that passes an audit. The goal is a firewall that actually protects your environment under the conditions it runs in every day.

Firewall work done right requires more than knowing the platform. It requires understanding the network behind it, the traffic patterns it carries, and the threat surface it is actually meant to address. HNI brings that engineering depth to every firewall engagement, whether it is a new implementation, a rule set review, or an architecture redesign for a network that has grown past its original design.

  • Design firewall architecture around how your network is actually built, how traffic moves, and what needs to be isolated.

  • Implement and configure Cisco and Palo Alto platforms with rule sets built around your real operational requirements.

  • Review existing firewall policy for outdated rules, misconfigurations, and exposure points that have accumulated over time.

Security Assessments

Understanding Your Exposure Before It Becomes a Problem

You cannot defend what you do not understand. HNI conducts security assessments that give organizations a clear, accurate picture of where their environment is exposed and what needs to change. We assess network architecture, firewall configuration, access controls, and security policy to surface the gaps that are most likely to matter, not just the ones that look bad on paper. The output is actionable, specific, and based on what is actually deployed in your environment rather than a theoretical model of what it should be.

A security assessment from HNI is not a checkbox exercise. We assess what is actually deployed in your environment, how it is configured, and whether it is doing what it is supposed to do. The output is a clear picture of where your exposure is greatest, what is driving it, and what a realistic remediation path looks like given how your environment is actually built and operated on a day-to-day basis.

  • Assess network architecture and firewall configuration to identify where your actual exposure is concentrated.

  • Review access controls, segmentation, and policy to surface gaps that create risk without obvious symptoms.

  • Deliver findings with enough context to understand what each gap means and what it would take to close it.

Security Policy and Management

Keeping Your Security Posture Tight and Well-Maintained

Security is not a project you complete. Rule sets grow, access accumulates, configurations drift, and what was locked down at deployment gradually becomes something less certain. The security posture you assessed last year is not the same one running today unless someone has been actively maintaining it. HNI manages security policy on an ongoing basis for organizations that need someone with real engineering depth watching their environment and keeping it in the condition it is supposed to be in.

Ongoing security management means more than running a scan and generating a report. It means maintaining your firewall policy, reviewing access controls on a regular schedule, catching configuration drift before it becomes exposure, and flagging anything that has changed in a way that creates risk. HNI handles this work for organizations that need engineering-level oversight, not just monitoring tools.

  • Review access controls and permissions to ensure that what people can reach matches what they should be able to reach.

  • Track configuration changes over time and surface anything that has drifted from the intended security baseline.

  • Maintain firewall policy on a regular cadence and flag rule drift before it creates unintended exposure.

Why Businesses Choose Us To Handle Their IT Strategy

Organizations that work with HNI share a common background: prior IT providers that executed well but never asked the right questions, or advisors who recommended without doing the work. HNI is built to do both, and that combination is not easy to find.

  • Advisory and Execution

Most IT partners either think strategically or execute well, but rarely both. HNI does both. We bring advisory depth to every engagement and the engineering experience to actually follow through on what the plan calls for.

  • Real Operational Depth

The experience HNI brings is not theoretical. Over 20 years of hands-on network engineering and more than 15 years of firewall and security work backs every recommendation, every design decision, and every advisory call we make.

  • Proven in the Field

HNI has spent years inside enterprise and public sector environments where precision matters and getting it wrong is not an option. That operating context shapes how we think, how we assess situations, and how we execute.

  • We Focus On The Results

We don't measure success by what we delivered or what we documented. We measure it by whether things actually got better. When something isn't working, we will tell you before you need to bring it up.

FAQs About Our Cybersecurity Services

What Is the Difference Between a Firewall Audit and a Security Assessment?

A firewall audit looks specifically at your firewall configuration, rule sets, and policy. A security assessment is broader. It looks at your overall security posture including network architecture, access controls, segmentation, and how your security tools are configured across the environment. HNI can do either, or both, depending on where your organization is starting from.

How Does HNI Approach Firewall Rule Set Reviews for Existing Client Environments?

We start by understanding the network the firewall is protecting, not just the firewall itself. That means looking at traffic patterns, segmentation, and what the rule set was originally designed to do before evaluating whether it still does that job. Rules are assessed for accuracy, necessity, and whether they create exposure that was not intended.

Does HNI Work With Organizations That Already Have Security Tools in Place?

Yes, and that is actually a common starting point. Most organizations have tools. The question is whether those tools are configured correctly and covering what they are supposed to cover. HNI works with what is already deployed, identifies gaps in configuration or coverage, and addresses what is actually creating risk.

How Often Should an Organization Review Its Firewall Policy and Security Configuration?

At minimum, firewall rule sets and security policy should be reviewed annually. In practice, any significant network change, new application deployment, or change in how users access systems is a trigger for review. Organizations in regulated environments or with active threat exposure should be reviewing more frequently than that.
