Thanks for the video. Nice stuff.
Once the JIT is enabled, are the admin accounts used to manage the on-premises AD using PAW use any password or is it passwordless/ FIDO/ Windows Hello?

In Sentinel, I'm able to decide which connectors to pull in events from (ie, not to pull in DLP incidents). I don't seem to have that same ability once I'm connected in the Unified Experience.
We have a separate team that generates hundreds of alerts per day for DLP policies that randomly get correlated with items we're looking at as Security Operations... and when we close our investigation, we close their alerts and mess up their stats and workflow.
If only we had a way to filter these out so they didn't get correlated. Similar to the toggle button we were given for IRM...

Microsoft Dependency Has Risks

This is not an opinion, this is not an opinion... it's an opinion, isn't it?
There was a recent incident where Microsoft somehow allegedly blocked a mailbox of a sanctioned individual. Any organization highly depending on MS products that might come into the crosshair should ask - can this happen to me? What would be the cost? How much I invest into prevention of this scenario? In this article I try to get the facts straight and…

A mostly good article, but to be honest, there are a number of things where I think you are wrong. One is: "From these, the email point seems to be most critical. In 2025, you really want a big provider to handle your emails - this point is so non-controversial that you have hosting companies advocating against hosting your own email."
Actually, letting a big provider handle my emails is absolutely the last thing I want - simply because, by design, they do it badly. If you want someone else to decide what you should and should not receive (in the name of blocking spam) - fine. If you want your incoming mail to be randomly tossed in the digital bin, without either the sender or yourself having any clue that's happened - fine. If you want to be subject to someone else's whims as to what's acceptable - fine. And as you point out in the blog, if you want to be subject to being disconnected "because ..." - fine If you want to be at the risk of your account (and all the email in it) to be deleted (whether by accident or malice) - fine. If you are fine with all of these then go ahead and trust your email to someone else and someone else's computer.
OK, I'm a techie and been in It for <cough> decades. But it actually isn't hard to run your own mail server. And if you do, then you can decide your own policies as to what is and isn't spam, and the biggest for me is that you can filter mail the only sane way (and which AFAIK not one of the big providers does) - and that is to decide whether it's going to be delivered, and if it isn't then you don't accept it. Lest there be any doubt there - AFAIK every large provider will accept mail (so to the sender's mail server "it's been delivered") and then throw some of it away.
Of course, someone with services to sell will egg up the problems. DNS is not hard. SPF is not hard. DMARC is not hard. Staying off blacklists is not hard (if you are only handling your own traffic, and generally not too much of a problem if doing it for clients). It is true that the big providers are more than happy to put blocks in the way of small providers (they'd rather you gave them money to mis-manage your email) - but in more than 2 decades of running my own mailserver (and with a previous work hat on, running one for clients) there have been relatively few issues. In general, the hardest part (running my own mail, on my own server at home) has been finding the forms the various providers have to say "actually, this is a real mailserver at this address" when blocked for being a "residential" address - but once found, I've found even AOL would accept my mail !
For good measure, I have access ot the unadulterated logs, and can turn up the logging level if needed to debug a problem.
I can understand hosting providers being against running your own mail servers. Firstly, again you usually are competing with a service they'd be happy to sell you. Secondly, I suspect that while it's not too onerous, there will be many clients who won't manage it and then expect the hsoting provider to sort out whatever mess they've got into. Other providers are simply against it because they think you should be paying them instead - but that's just business.
Lastly, there is one really REALLY important reason why any business (in Europe or the UK) cannot outsource it's email to the big providers - it is my opinion that it cannot be done legally !
I know that (for example) Microsoft will provide assurances that you can, you can arrange for all your data to stay within Eurpoean data centres, and so on. But you hinted that DNS is hard - and if you use Microsoft's mail systems, then the domain microsoft.com is involved. That is under US control, and so in the US they have the power to direct your login and authentication anywhere they want - e.g. they could collect an authentication token to give themselves access, or just plain route you through a dummy sign-in and harvest your credentials. Now, if someone has that level of control, can you tell me my data is 100% safe from them ? And if it isn't, then it's illegal under European and UK data protection laws to put any personal information (and that will include email) at that risk. Perhaps I'm just paranoid, but we've seen Microsoft hand over data held in data centre in Ireland as soon as the CLOUD act was passed.

Dinosaur leaders seen off by being out of step

ALSO: Microsoft says we're living an infinite workday
You might vaguely remember the headlines last year when Seb James, the CEO of Boots announced that working in the office was proving so ‘fun and inspiring’ that he’d decided to give an inflation busting fun rise to all employees. Boots office employees would be back in the office five days a week by the the end of the summer

Hi Bruce, thank you for this insightful post. I'm training to be a nurse in the NHS after many years in corporate and NGO desk-based jobs. It has been quite profond to see the impact of effective teamwork, senior staff role-modelling behaviour and a culture of learning on quality of care, performance and staff morale. I'm talking about some wards/units - not all of course. I am also reminded of something an American friend said to me recently in discussions about hierarchy and team-work; "Some people kiss up and kick down, some people kick up and kiss down"...now I wonder what gets the best results?....

Outside of USA I'm sure savvy people have been drifting away from MS for a long time. I haven't used Outlook in years, or any office product at home for... I can't remember how long. Good move by Denmark. Trump doing a great job of isolating the US

I have been a fan of using open-source software for a while. I still use Microsoft Office 2007. I haven't used Office 365 due to pricing and privacy concerns. I think that this is a great decision.

Blackrock is known for politicizing capitalism Leftward. In my opinion, the Lefties naturally support fiat and oppose hard money Bitcoin, because they siphon the value off of the fiat, and use it for Lefty social engineering and vote buying.
