A researcher has published an unverified proof-of-concept claiming a zero-day privilege escalation in CrowdStrike Falcon Sensor dubbed FalconFlank. It reportedly abuses Falcon's Office macro remediation workflow to escalate from a low-privileged local user to SYSTEM.
Important context: CrowdStrike hasn't confirmed it. No CVE exists. No independent researcher has verified the exploit chain. Treat it as unconfirmed, not urgent.
But it's a useful reminder of a structural truth in endpoint security: EDR agents run with elevated privileges by design, because they have to quarantine, restore and remediate. That privilege is exactly what makes the agent itself worth watching, not just trusting.
It's why we don't treat any single agent as the final word on an incident — endpoint, identity and network signals get correlated before anything is called confirmed. One control shouldn't be both the thing that protects you and the only thing that tells you if it's failed.

A calm, evidence-led read of the FalconFlank claim against CrowdStrike Falcon Sensor: what's confirmed, what's unverified, and a practical response plan for MSPs and their clients.

Your customers need 24/7 cybersecurity.
That doesn’t mean you need to build a 24/7 SOC.
Recruiting analysts, introducing out-of-hours shifts and investing in security technology can cost hundreds of thousands of pounds before you protect a single customer.
Custodian360 gives partners access to an established UK-based SOC, experienced analysts and genuine managed detection and response, without the cost and complexity of building it themselves.
You retain the customer relationship. We provide the security capability behind it.

One of the biggest myths in cybersecurity?
That good protection is only for big businesses with big budgets.
It isn't.
Most small and growing businesses don't need a security team of 20 people or a room full of expensive technology.
What they need is sensible protection that matches their size, their risks and the way they work.
The right advice.
The right support.
The right technology.
Nothing more.
Cybersecurity should be accessible to every business, not just the largest ones.
That's what we believe at Custodian360.

Cybersecurity should not keep you awake at night.
Yet for many businesses, it does.
Not because they do not care about security, but because they are busy running a business. Looking after customers. Managing staff. Winning new work. Keeping everything moving forward.
That is where we come in.
At Custodian360, we help take the stress out of cybersecurity. No jargon. No scare tactics. No pressure to buy a pile of expensive tools you do not need.
Because good cybersecurity is not just about technology.
It is about people.
It is about having experienced humans who can help you understand your risks, make sensible decisions, and be there when you need support.
The best security solutions combine great technology with real human expertise. One without the other is rarely enough.
Whether you have 10 employees or 1,000, cybersecurity does not have to be complicated, overwhelming, or unaffordable.
It all starts with a conversation.
So if cybersecurity has been sitting on your to-do list for far too long, why not make today the day you change that?
Come and talk to us. You might be surprised just how easy cybersecurity can be.

Cyber criminals don't work office hours.
Which means cybersecurity can't stop when the working day ends.
Many businesses invest in great technology but nobody is watching when alerts happen overnight, at weekends or during holidays.
That's often when problems become incidents.
Good cybersecurity isn't just about having the tools.
It's about having people ready to act when something needs attention.
Because security after 5pm still matters.

Do MSPs really need to build their own SOC to offer managed security?
In many cases, the answer is no.
Building a genuine 24/7 SOC requires significant investment in skilled analysts, technology, processes and round-the-clock coverage.
Partnering with an established SOC can provide a faster, more scalable route, allowing MSPs to meet growing customer demand while retaining the relationship and creating recurring revenue.
Your customers need protection around the clock. You don’t necessarily need to build the entire operation yourself to deliver it.

"We're too small to be a target."
It's one of the most common things we hear.
The reality is that most small businesses aren't ignoring cybersecurity because they don't care.
They're ignoring it because they're busy.
Busy serving customers.
Busy managing staff.
Busy chasing invoices.
Busy growing the business they have worked so hard to build.
Cybersecurity often ends up becoming tomorrow's problem.
Until tomorrow arrives.
The good news is that protecting your business doesn't have to mean hiring a security team or investing in expensive technology.
Sometimes it starts with understanding what you already have, identifying the gaps, and putting a simple plan in place.
No panic.
No scare tactics.
No unnecessary spending.
Just practical steps that make your business safer and more resilient.
At Custodian360, we believe cybersecurity should be accessible to every business, not just large enterprises with huge budgets.
If you've been putting it off because it feels too complicated, too technical, or too expensive, let's have a conversation.
You might be surprised how much can be achieved with the right guidance.
Cybersecurity doesn't have to be difficult.
It just has to start somewhere.

Most business owners don't lie awake worrying about hackers.
They worry about customers.
They worry about staff.
They worry about paying suppliers, winning new business and keeping everything running smoothly.
That's exactly why cybersecurity matters.
A cyber incident isn't just an IT problem.
It can mean:
• Lost income
• Lost productivity
• Lost customer trust
• Lost time trying to put things right
For many small businesses, the biggest cost isn't the attack itself.
It's the disruption.
The hours, days or even weeks spent recovering when you'd much rather be focusing on your customers and growing your business.
The good news?
Most cyber incidents can be made far less likely with a few sensible steps and the right support.
Cybersecurity doesn't need to be complicated.
It doesn't need to be expensive.
And it certainly doesn't need to keep you awake at night.
At Custodian360, we help businesses build practical, affordable protection that works in the real world.
Because your time is better spent running your business than worrying about cybersecurity.
📞 It starts with a conversation.

Buying a security product and installing it is only the beginning.
Software doesn't investigate alerts.
Software doesn't understand your business.
Software doesn't pick up the phone and explain what's happening.
Technology is incredibly powerful.
But technology without people is only part of the answer.
The businesses that stay safest combine great tools with experienced humans who know what to look for and what to do next.
Installed doesn't always mean protected.
