Weird, but not surprising because holy hell some people just really can't stand the idea that any mail would ever be dropped for any reason and are incredibly paranoid that they might miss an e-mail.

yeah. the reality is the user will never see it, but iirc quarantined messages like that can be released to the recipient where rejected messages are gone. its a fine compromise I guess.

there's not really any vendor that does everything like cisco does so unless you want to manage 4-5 different network operating systems just to keep the lights on it's a pretty good sell regardless of how terrible it is

speaking of the invoicing fraud, apparently one of the more profitable scams has been to email or call buyers and escrow agents near the closing date of a property sale with updated wire transfer information.

the fake invoices thing is a little funny because it’s a case of everything old being new again that sort of thing is like half the reason your accounts payable position exists to begin with then, once the AP clerk determines the invoice is legitimate and the goods have been received, they put it in a pile until it’s at least 60 days overdue

A lot of large financial transactions in Fortune 50s is via ACH transfers started by paper, usually emailed. Easily spoof the sender, change the bank details, and most Finance Execs dont double check with who sent the request. There is so much implicit trust based around the email of the person who made the request. Dont ask how I know this....

Down in Kiwi telco land Juniper rules, Cisco's only really enterprise/corporate and I think that translates to the AU too

juniper makes good routers which is why they are big in the telco space, where you need big routers and little else. cumulus and arista have taken over modern data centres so I would say you're pretty much spot on (enterprise/corporate is still a massive space ofc)

20-ish sites nationwide lost their primary internet and site-to-site VPN connections for ~30 hours because those two groups spent three months arguing about whether or not the at&t bill needed a PO before it would get paid. Procurement claimed it didn't, because it wasn't tied to a contract, it was a recurring utility bill. AP said it did, because  The final bill to get everything online was 6-figures.

actually how do you even dump a USB flash drive given it could have a CPU running an OS that detects behavior and wipes the flash irrespective of any write-blocking dongle in between the PC and the flash drive
