How long does it take to move firewall management to a new provider?

Two to six weeks for a typical single-site environment, and longer when you have multiple locations, a segmentation rebuild in scope, or production equipment that only tolerates a change window at 2am on a Sunday. The inventory and rule audit take the first week or two. Cutover itself is usually one scheduled window.

Do we have to buy new hardware?

Not automatically. Supported hardware with life left on it stays. Replacement is recommended when the end-of-support date is inside 18 months, or when the device can't run current firmware.

What's the difference between a managed firewall and a next-generation firewall?

One is a product, the other is a service. A next-generation firewall is the hardware or software, with application awareness and intrusion prevention built in. Managed firewall is who runs it. You can own an excellent next-generation firewall and still be exposed if nobody is patching it.

Can you manage the firewall brand we already own?

Usually. Consilien works extensively with WatchGuard, Cisco, and Cloudflare, and supports the other mainstream platforms. If a model is close to end-of-support, that gets raised during the inventory rather than after the contract.

How fast do you patch when something critical comes out?

Faster than the scheduled window. Anything landing on the CISA Known Exploited Vulnerabilities list for a managed device triggers out-of-cycle patching rather than waiting for the next maintenance date. The Verizon 2026 DBIR put the industry median at 43 days to full remediation.

Managed Firewall & Network Security Services

Firewalls that stay patched, get replaced before support ends, and are built to contain a breach instead of forwarding it.

Managed firewall services put an outside team in charge of your firewall's rules, monitoring, firmware updates, and replacement schedule. Consilien covers all four. A lot of providers only cover the first two. That gap is where a growing share of network breaches now starts.

Something Changed in the Last Year

For the first time in the report's 19-year history, stolen credentials are not the top way attackers get in. The Verizon 2026 Data Breach Investigations Report, published May 20, named something else. Vulnerability exploitation, at 31%.

And inside that group, breaches that began at an edge device or VPN gateway climbed from 3% to 22% in twelve months. An edge device is just the hardware sitting between your network and the internet. Your firewall. Your VPN box. Your router.

The equipment you bought to keep people out became one of the more likely places they get in.

The clock got slower at the same time. Median time to fully remediate a known vulnerability moved to 43 days, up from 32 the year before. And only 26% of the vulnerabilities on the CISA Known Exploited list were fully remediated across the 13,000 organizations polled, down from 38%.

Wider exposure window. Faster exploits. Bad combination. That's the squeeze this service is built around, and it's the slice of our managed cybersecurity program that touches every other piece.

The Advice Everyone Repeats Stopped Being True

There's a line on nearly every managed firewall page you'll read this week. Gartner predicted that through 2023, 99% of firewall breaches would come from misconfigurations, not firewall flaws.

That prediction had an expiration date. It was 2023.

Misconfiguration is still a real problem, and any provider worth hiring will audit your rule set, because a firewall carrying nine years of accumulated rules nobody has reviewed is doing a fraction of the job it was bought to do. But a page that leads with a forecast whose window closed three years ago is describing a threat model the 2026 data has already moved past. The flaw in the box is now the bigger door.

A managed firewall service is an ongoing arrangement where a provider owns your firewall's configuration, rule changes, monitoring, firmware patching, and hardware replacement schedule. You keep the business decisions. They keep the device current, the rules clean, and the logs watched. What varies wildly between providers is how much of that list they actually do.

What's Actually Managed, and What Usually Isn't

Ask three providers what managed firewall includes and you'll get three answers. Here's how the scopes typically break down.

	Consilien lifecycle program	Monitoring-only managed firewall	Handled internally
Rule and policy changes	Included, with documented change history	Included, often ticket-limited	Yes, if someone has time
24/7 traffic monitoring	Included, tied into our SOC	Included	Rarely
Routine firmware patching	Included, on a scheduled window	Sometimes, often on request	Inconsistent
Emergency out-of-cycle patching	Included	Usually not defined	Depends who's on call
End-of-support date tracking	Tracked per device and reported on	Almost never	Almost never
Hardware refresh planning	Planned before the support date lands	Not included	Reactive
Network segmentation design	Included	Not included	Occasionally
Log retention for audits and insurance	Retention matched to your compliance requirement	Varies	Often 30 days or less

Comparing providers? We scored the firms in this category against a published model.

The rows that matter most in 2026 are the four in the middle, and they are the ones that quietly separate a provider who keeps your hardware current from a provider who just watches the traffic going through it. They're also the four most likely to be missing from a contract you're already paying for.

Go pull yours. Search it for the words firmware, end-of-support, and emergency. If none of them appear, you have a monitoring contract, not a lifecycle contract. Two different things.

Your Firewall Has an Expiration Date

One thing that comes up a lot. Companies know exactly when their Microsoft licenses renew, when the copier lease is up, and when the building insurance gets rebid, but almost nobody in the room can tell you the date their firewall stops receiving security updates. Same building, same budget, very different level of attention.

That date is real. And it's close for a lot of hardware. The Cisco ASA 5506-X, 5506H-X, 5506W-X, 5508-X, and 5516-X reach last day of support on August 31, 2026. After that, a critical vulnerability in one of those units doesn't get a patch. Ever. The only fix is replacement.

Plenty of them are still online. Shadowserver counted close to 50,000 internet-facing Cisco ASA and FTD instances vulnerable to two actively exploited flaws in September 2025, with more than 19,000 of those in the United States. Still plugged in. Still facing the internet.

The federal government stopped treating this as a maintenance issue. CISA Binding Operational Directive 26-02 now requires civilian agencies to inventory every end-of-support edge device within 90 days, decommission the identified ones within 12 to 18 months, and stand up continuous discovery within 24 months. Separately, Emergency Directive 25-03 gave agencies 24 hours to patch the Cisco ASA flaws, against a normal three-week window.

You aren't bound by any of that. Your cyber insurance underwriter is reading it, though.

A firewall nobody patches is a router with a bigger price tag.

When we take over an environment, the first two things we pull are the firmware version and the end-of-support date on every edge device. Then we put both on a calendar with a budget line attached.

How the Engagement Runs

Five stages. The first one usually surprises people, because it's mostly counting.

Inventory and exposure review

We list every firewall, VPN concentrator (the box that terminates remote connections), and internet-facing device you own, with model, firmware version, support status, and end-of-support date. Then we scan what's actually reachable from outside.

Rule and policy audit

Old rules pile up. We map every rule to a business reason, flag the ones nobody can explain, and remove what's dead, which on a firewall that has been in service since the last refresh usually means a third of the rule set goes away. Any-any rules, the ones that let anything reach anything, get named out loud.

Segmentation and design plan

We design the internal boundaries, so a compromised device reaches one room instead of the whole building. Production, finance, guest Wi-Fi, and vendor access get separated on paper before anything changes.

Cutover and hardening

We rebuild the configuration to a documented standard, turn logging on, and point it at retention. Your operations team picks the window. Nothing goes in on a Friday afternoon.

Ongoing lifecycle management

Monitoring, rule changes, scheduled firmware updates, emergency patching when something on the Known Exploited list lands, reporting on support dates, and a refresh plan that arrives before the device expires rather than after.

Everything here maps to our CIMS maturity standard, which is how we keep environments consistent across clients. It usually starts with an IT assessment.

The Questions That Come Up Before Anyone Signs

These are the questions that come up in the room, usually right before someone asks for a number.

Segmentation Is What Keeps One Bad Device From Becoming a Bad Quarter

Here's the uncomfortable arithmetic of a flat network, where every device can talk to every other device because nobody ever drew a line between them. One compromised laptop, one exploited VPN appliance, and the attacker can reach the file server, the ERP box, and the backup target from the same position. No second door to get through. No alarm in between.

Network segmentation breaks that. The firewall at the edge controls what comes in. Segmentation controls what can move around once something is already inside, which is the part that decides whether a single compromised laptop becomes an incident report or a full production outage. Two different jobs. Providers who only sell you the first one are solving half the problem.

Underwriters figured this out before a lot of buyers did. Segmentation now shows up alongside multi-factor authentication on standard control checklists, and it gets asked about specifically for manufacturers, utilities, and defense contractors.

Running unsupported equipment cuts the other way. Carriers can and do reduce or deny a claim when a forensic review finds a known vulnerability sitting on an end-of-life device. The premium isn't the exposure. The denied claim is.

What Managed Firewall Services Cost

Almost nobody publishes this, so here's the structure at least.

Managed firewall pricing is built from four things. The count of firewalls under management. The number of physical sites. Whether the hardware is yours or ours. And how long you need logs retained, because retention is storage and storage is a real cost that scales with every month you're required to keep the data.

What moves the price	Why it moves it
Number of firewalls	Each one is a separate device to patch, monitor, and track a support date against
Number of sites	Encrypted links between offices, plus the time it takes to get someone physically on site, both scale with locations
Hardware ownership	Buying it yourself lowers the monthly and raises the up-front. Ours does the reverse.
Log retention period	30 days is standard. Compliance frameworks often want 12 months, which changes storage cost
After-hours change windows	Manufacturing and distribution clients frequently need cutovers at 2am, which is priced differently
Segmentation scope	A flat network being carved into 6 zones is design work, and it's one-time

Common Questions About Managed Firewall Services

Is a managed firewall worth paying for if we already have an IT person?

Often yes, and the reason isn't skill. It's coverage. One person can't hold a 24-hour patch window, an on-call rotation, and a hardware refresh calendar alongside their day job. Co-managed arrangements are the common landing spot here, where your person keeps the business context and we take the pieces that need to happen at 3am or on a holiday weekend.

Find out what's actually running at your edge, and when it expires.

Every month an unsupported firewall stays online is a month where a published vulnerability has no patch behind it. The inventory takes a couple of hours and it's the same work either way, whether you hire us or hand the list to your current provider.
