Most Security Advice Isn’t Just Outdated. It’s Wrong.
A great deal of Cybersecurity content from five or six years ago is uncomfortably outdated, and in fact, some of it you’d actively warn a customer to avoid. This isn’t because the old advice was careless. The threat landscape underneath it has simply shifted.
That’s not a hypothetical. It’s the state of older security content sitting on vendor and Advisor sites right now. We need to properly compare what the guidance used to say against what’s actually true today.
The gap between the two is where a Trusted Advisor makes or breaks their credibility, although the core tenets of cybersecurity remain: protect data, protect its truth, keep it available, verify who gains access, and prove what happened.
Then: “Turn On 2FA and You’re Covered”
For years, the standard advice was to enable two-factor authentication, ideally via an SMS system, and you’d close the door on being compromised. That was reasonable in 2020.
It is not reasonable in 2026.
SMS-based and app-push MFA are routinely bypassed these days through MFA fatigue attacks (bombarding users with push approvals until one is accepted) and adversary-in-the-middle kits that intercept one-time codes in real-time. Token hijacking at the browser level is another pathway to being compromised, with credentials left sitting in browser tokens waiting for cybercriminals to seize them and gain access.
Current guidance isn’t to simply enable MFA anymore. You need to enable the right MFA, particularly phishing-resistant methods like FIDO2 hardware keys. Cyber insurers are paying closer attention to MFA deployment, and not just whether it’s turned on. Some of them – Coalition, for example – are calling SMS “by far the weakest type of MFA available.”
If a piece of Advisor content tells customers that SMS-based 2FA is a solid stopping point, it’s steering them toward a control attackers already know how to breeze through.
Then: “Ransomware Is an Emerging Threat”
Dated security content tends to frame ransomware through a mid-2010s lens. Think of an opportunistic yet unsophisticated single attacker encrypting files and asking for payment.
That threat has industrialized.
Today, we’re dealing with ransomware-as-a-service run by organized syndicates. Initial-access brokers sell entry points to specialists who deploy the payload. The number of recorded ransomware victims worldwide increased by 32% from 2024 to 2025, and total global damage from ransomware in 2026 is expected to top $30 billion, which is actually the most conservative estimate out there. Other projections put the number at $74 billion.
New incidents also leverage AI, including deep-fakes deployed to authorize fraudulent transfers, or AI-assisted phishing that’s hard for even well-trained employees to spot.
Trusted Advisors can no longer tell customers here’s what ransomware is and leave it at that. Now they need to know how fast a ransomware operation can move and why their recovery plan matters as much as their prevention plan.
Then: A Framework Snapshot. Now: A Different Framework.
Security research content anchors itself to a compliance framework at an exact point in time, and that’s why it needs constant revisiting.
NIST’s Cybersecurity Framework was substantially rewritten in February 2024. CSF 2.0 did more than just tweak the language. It added an entirely new function – Govern – that sits above the original five (Identify, Protect, Detect, Respond, Recover), and expanded the scope from critical infrastructure to organizations of every size and sector. Govern pertains to who owns the risk, and how it ties to strategy and supply-chain oversight.
Any security content built around the pre-2024 Framework has been superseded. A customer being advised on the old five-function model is missing something regulators and cyber insurers expect, which is how organizations go about governing security decisions and how they respond to breaches.
Then: Keep Attackers Out. Now: Assume They’ll Get In.
Older security content treats networks like a fortress. You can keep everything inside safely protected if you use firewalls, VPNs and antivirus to build a strong enough barrier.
Users, applications and data now live within cloud platforms, home offices and personal devices. That content assumes a perimeter that hardly exists – and cybercriminals know it! The real question is how far they can get once they’re in.
The truth is that it’s fast and far. Cybercriminals are moving from initial access to other systems in an average of 29 minutes, with the fastest observed case landing at just 27 seconds, according to CrowdStrike’s 2026 Global Threat Report.
Current guidance assumes a breach will happen. That means building zero-trust architecture that verifies every user and device on every request, segmenting networks, users and devices so one compromised account can’t reach anything else, and 24/7 detection and response that can contain an intruder in minutes instead of days.
For Trusted Advisors, this changes the customer conversation. How do we keep them out? is no longer sufficient. The better question is If they get in at 2 am, what stops them?
What This Means for How We Talk About Security
This is a time for precision, because your customers know the difference between a real shift and fake vendor urgency. Security guidance has a shelf life, and pretending it doesn’t is how a Trusted Advisor ends up handing a customer a five-year-old roadmap.
Advisors who maintain security credibility going forward can speak to what changed and why it matters without reciting a checklist. This is exactly the kind of gap AVANT is positioned to close with fresh guidance grounded in the current threat and compliance landscape, delivered with the same rigor as our other AVANT Analytics research.
That’s why AVANT built its Cybersecurity Assessment Tool on CSF 2.0, Govern included. Inside Pathfinder, it guides you through a structured conversation with customers, covering everything from devices and applications to network, data, and users. As you work through it, a live Cyber Defense Matrix fills in. It shows what your customer already has in place, where there’s an opportunity to upgrade, and where the gaps are, including critical ones needing attention now. The assessment also covers not just how to prevent an attack but also what happens afterward, from incident response planning to backup and recovery.
Behind the scenes, the tool estimates the annual value of each opportunity based on your customer’s size, so you know where to focus before you walk into the next conversation. When you’re ready, you can export a PDF that compares your customer’s current posture with where it could be. One click brings your AVANT team in to help with next steps. And because security guidance has a shelf life, every assessment is saved, so you can revisit it as your customer’s environment changes.
Cyber threats don’t wait for content calendars. Nor should the advice we provide.
