Planned Approach to Renting vs Leasing Next Generation Firewalls (NGFWs)

I began my career as a network admin in 1993—yes, before people had any real concern for network security as we know it today. I recall struggling with voice and data muxes that rode over PSTN lines and rushing to patch systems during the outbreak of the Slammer worm. I learned on those occasions that in cybersecurity (and cooking) timing and the proper ingredients matter — a lot.

Now, in 2024, I own my own consulting business and it has been a crazy journey. I’ve recently assisted three banks in redesigning their zero-trust architectures: Proof that it is worth holding nothing sacred, especially in fintech. Just back from DefCon myself, and hot damn, that hardware hacking village made me queer to death how much tech is still a yawning white hole of insecurity.

Today, I want to cover a topic that isn’t as sexy but just as important to maintaining your secure posture: the distinction between renting and leasing next generation firewalls (NGFWs). It’s a subtle distinction but one that can make a big difference — not just in your bottom line, but also in your security defenses.

1. Definitions & Tenure

Let’s make it way simple. When you rent NGFWs, it’s typically short term, and you pay for usage. It’s as if you were to borrow a high-end car for a weekend — excellent as far as spur-of-the-moment need is concerned, or as a way to test-drive a ride before you buy. Rentals are most commonly a few months to a year.

Financing, on the other hand, is kind of a long-haul transaction. It will be like signing a 3-5-year lease on a car that you’ll want to use regularly, but don’t need to actually own outright. It’s financially structured, lengthier and often with maintenance and upgrade agreements.

Why does tenure matter? Here’s the kicker: cybersecurity solutions like NGFWs change quickly. If you’re renting, you have the freedom of the latest tech without the commitment but you may be paying a premium. Leasing locks you into a contract but commonly lowers monthly fees and allows you to budget your security spend.

2. Balance-Sheet Impact

This is where most CFOs perk up — or cringe. Leasing will usually be an operational expense (OpEx). This means it goes directly onto your profit and loss statement – great if you’re trying to keep a cap on CapEx.

In some situations, financial leases can even be considered capital expenditures (CapEx). That hits your balance sheet differently — it’s an asset and a liability. This may all sound like accounting mumbo jumbo, but it affects your company’s financial ratios, borrowing ability and tax treatment.

Short story: I told a mid-sized bank to lease their firewalls, not rent, and they were able to leverage tax credits and increase cash flow. But for a start-up I recently worked with, it made more sense to rent, because of their unpredictable growth and shifting tech needs.

Some quick bullets to consider:

• Leasing = OpEx, flexible, short-term, higher monthly cost.
• Lease = CapEx or mixed accounting treatment, non-customer service users, fixed long-term costs, possibly for tax.
• Your finance team will love if you get this one right.

3. Buyout Options

There’s usually a buyout in leases. That’s akin to the option of buying your leased car at the end of the term, some times at a discount. It’s a useful choice if you’d like to continue using that same NGFW and not attack finding new vendors or setups.

Rentals almost never extend buyout options — again, short-term utility and return. But some also let you move from rentals to leases along the way, if you find that the solution really is the right one for your environment.

My experience has been that buyouts are a two-edged sword. One client I had witnessed a pretty bad lease buyout over older technology because of lack of understanding of how fast features became obsolete. Lesson? And always, always, negotiate those terms up front and know your upgrade path.

4. Early Termination Fees

Here’s a hidden minefield. Leases often come with terms that you’ll be stuck with — or find yourself paying high early termination fees to escape. Think about it: You sign up for a 5-year lease and then security requirements change due to new regulations or a ransomware incident. Missing out early can be very costly.

Rentals are more flexible here — often at short notice, even pay-as-you-go in some cases. But beware — if you temporarily rent devilishly cheap firewalls temporarily, you may not get full support or the latest firmware.

Been there, done that. I recall a client in 2003 that pushed through a firewall lease only to abandon it 18 months later, when new zero-trust guidelines were issued and they were faced with giant fines. The safer path? Consider every scenario that might change and how it may affect your agreement before you sign.

5. Decision Checklist

All right, here’s where I save you the headache. If time is tight with your team, then skim this —

Quick Take:

• How long should your firewall last? (Short burst = rental, long haul = lease.)
• To what extent do you have cash-flow constraints? Cash strapped? Rental might be smarter.
• Do you care if you can own the gear? Leases usually offer buyouts.
• Are your security needs changing quickly? Rental’s flexibility shines here.
• How do you feel about early termination fees? If not, rent-lean or carefully negotiate lease exits.
• Finance folks involved? OpEx impact vs. CapEx? Be sure you’re clear on this.

And because I’m a sucker for an analogy—how about if you rent an NGFW it is like borrowing a pressure cooker to cook a big family dinner. You don’t want to spend the money on one if it’s going to be a dust collector. Leasing? It’s like renting a truck on a lease for long-line deliveries, you’re in it for the long haul, need something that’s reliable, and want to know exactly how much money you’re going to be spending.

But — and this is key — when it comes to a rental firewall vs lease, it’s not just about the money. It reflects your security strategy. Your firewall is more than just a gate, it’s a sentinel defending your network. So, “fast” in-and-out rentals could leave you holding the bag juggling firmware versions or without vendor support.

One more thing, I swear I will let you go—password policies won’t secure your leased or rented firewall. Do not be seduced by easy-to-entice users with their lazy attitudes towards changing passwords just because your firewall is technically ‘managed’. It’s like having bought a fancy car but never having changed the oil. Doesn’t work.

At the end of the day, choosing between renting and leasing NGFWs must fit into your overall cybersecurity roadmap AND your financial plan. Don’t just choose whatever might sound cheaper now – the expenses of switching halfway through, of missing out on upgrades, or of finding yourself locked into bad contracts later on will get ya.

So, and this is my third coffee and I’m off the plane from Vegas cross-continental, and that’s my take: not one size fits all. But informed choices? They keep your network — and your sanity — running smoothly.

Stay sharp,
