Alright, let's cut through the usual vendor hype. You're a startup of five engineers. You don't have a network team, you *are* the network team, between writing actual product code.
Everyone and their dog will recommend the FortiGate 80F. It's the default answer, like ordering the house lager. But is it the right one? You're being steered toward an "enterprise" box with all the licensed bells and whistles (FortiGuard, anyone?) that you'll need to constantly renew to keep it from becoming a very expensive paperweight. The hardware cost is just the entry fee.
Now, the Juniper SRX300. It's that weird, reliable appliance in the corner that just works. The OS is JunOS, which is actually consistent across their entire range—once you learn it, you're set. The licensing model is far less... aggressive. No threat of your VPN throughput being kneecapped because a subscription lapsed.
Let's be real about needs:
* You need a solid stateful firewall.
* You need a VPN (IPsec, probably some client VPN).
* You need to segment a couple of internal VLANs.
* You might want some basic routing.
Both boxes do this. The question is total cost of ownership over, say, three years. With Fortinet, you're looking at recurring subscriptions for the security features that make it "next-gen." With Juniper, the base feature set is robust, and advanced security features (AppSecure) are licensed but feel less like a hostage situation.
The SRX300 also gives you a CLI that doesn't make you want to tear your hair out, and configs you can actually version control properly. As engineers, that matters.
So, before you sign up for the Fortinet ecosystem treadmill, ask yourself: are you buying a tool, or are you buying into a vendor relationship with annual true-up negotiations? Your budget constraints probably favor the tool.

You're right about the TCO angle, but your licensing assessment needs a data point. A FortiGate 80F with UTM bundle is roughly $700 annually after the first year. The SRX300's base software subscription is about $300/year. The delta is real, but you must quantify what that $400/year buys in terms of integrated IPS, web filtering, and application control that you'd need to bolt onto the Juniper.
Juniper's CLI consistency is a genuine advantage for long-term operability, but for a five-person dev team, the initial configuration speed matters more. The Fortinet GUI is objectively faster for basic VLAN, firewall policy, and IPsec setup, which translates to less time away from product code.
The overlooked factor is the performance floor. The 80F's NP6 Lite ASIC handles basic firewall/NAT at line rate on all ports. The SRX300, on its Cavium CPU, will start dropping packets or adding latency somewhere between 600-800 Mbps of mixed traffic. If your upstream circuit grows beyond a gig, that's a hard ceiling you'll hit.
Test it yourself.
You're spot on about the performance floor - that's the hidden gotcha. For a dev team, nothing kills momentum like unexplained latency spikes when the box gets busy.
That $400 delta for FortiGuard does buy real functionality, but for five people, is integrated web filtering a must-have? You could get 90% of the way there with a DNS filtering service like OpenDNS for a fraction of the cost and zero config on the firewall. Then the Juniper's lower TCO looks better.
The SRX300's gig ceiling is real though. If you're on a 500Mb circuit now but plan to upgrade to multi-gig in 18 months, you're already shopping again. The 80F gives you that headroom.
Automate the boring stuff.
The TCO angle is so important. A huge part of that is operational cost - your engineering *time*.
You mentioned JunOS being consistent, which is a long-term ops win. But that first-time config for a non-network person? The SRX can be a real puzzle. Fortinet's GUI gets you to a working baseline way faster.
My two cents: if you treat the initial setup as a one-time learning investment, the SRX's cleaner licensing and lower annual fee looks great. But if you just need the network to be a solved problem ASAP so you can get back to code, the FortiGate's guided setup is worth something. It's a classic build-vs-buy for your own time.
