Like most things, in IT, CyberSecurity, and Web development, you get what you pay for.
If you take the lowest cost option, it will often cost more for those services in the long term (vendor keeps coming back asking for more money because they underestimated the amount of effort), assuming nothing goes tragically wrong…
What could go wrong?
A lot can go wrong - on the low end of the spectrum, the service that you paid for either doesn't work, or works poorly. Worst case scenario, you & your dog are in your car under a bridge.
Buy once, cry once.
We have seen customers that have gone with the cheap (or no) option, and have either been compromised, usually losing money, future business, and reputation, just for them to have to get someone to clean up the mess caused by the original vendor, which is usually expensive, or just start over fresh.
If your business is compromised, then the cost for remediation alone is around 10-20 years worth of protection, and that doesn't include the financial losses related to the compromise, or the lost business due to reputational damage.
So should I just buy the most expensive option?
No. Buy the option that works best for you. Just like you shouldn't buy a car from some brand that has only been in existence for 5 minutes, and will probably disappear in the next year, you probably don't need to buy a Bugatti. Look for the Toyota option. They're certainly not the cheapest, certainly not the most expensive, they aren't fancy, but they're reliable, and they have great after sales parts availability. (You can still buy genuine parts from Toyota for a 1960s vintage Landcruiser FJ40 series).
When you depend on something for your business' survival, it's not a matter of which vehicle you will choose, but which LandCruiser will you choose?
