Here are 16 cybersecurity courses I took during my learning journey, and they significantly deepened my understanding of the fundamentals.

🚨BREAKING: ANTHROPIC IS GIVING AWAY THE SAME CERTIFICATION THAT DELOITTE IS MASS-TRAINING 15,000 EMPLOYEES TO GET. It costs $0. You need a laptop. That's it. It's called the "Claude Certified Architect." Think of it like the AWS cert but for AI. If you were around when AWS certs started, you know what happened. They went from "cool to have" to "you're not getting hired without one." That took about 5 years. This is going to happen way faster. Look at who's already moving: Accenture - training 30,000 people on Claude Cognizant - rolled it out to 350,000 employees Deloitte - opened Claude access to 470,000 people Infosys - anchor partner These aren't startups experimenting. These are billion dollar consulting firms restructuring their entire workforce around Claude. And the certification they need? You can take it right now from your bedroom. Let me be real though. This is not one of those "watch 2 videos and get a badge" type certs that nobody respects. This thing is hard. 60 questions. 2 hours. Proctored. Webcam on. No breaks. No googling. They drop you into real scenarios like designing a customer support agent that handles refunds or setting up Claude in a CI/CD pipeline. The wrong answers look right on purpose. They're the exact mistakes real engineers make in production. 720 out of 1000 to pass. People who took it are saying the agentic architecture and multi-agent orchestration sections are brutal. Most of the exam is about building AI systems that actually work in the real world. Not prompting. Not chatting with Claude. Architecting production systems. All the prep? Free. Anthropic put out 13 courses on their Academy. No paywall. The cert itself is free for the first 5,000 people. After that $99 per attempt. How to get it: 1. Join the Claude Partner Network (free) → partnerportal.anthropic.com 2. Start the free prep courses → anthropic.com/learn 3. Register for the exam → anthropic.skilljar.com 4. Take the official practice exam 5. Book the real one when you're ready It launched 10 days ago. Almost nobody has it yet. That's the whole point. Get it before it becomes the thing everyone has.

Imagine this scenario. An employee is working on a report. They are under pressure and need to finish quickly. So they copy sections of a confidential financial report and paste it into tools like ChatGPT or DeepSeek to summarize the content or improve the writing. It feels harmless. But in that moment, sensitive company information may have just been shared with an external AI system A large percentage of employees are already using generative AI tools for sensitive tasks at work and many of them are doing it without their organization knowing. This is called Shadow AI. You may have heard the term before. If not, here is the simple breakdown. Shadow AI is the use of artificial intelligence tools inside an organization without the knowledge, approval, or governance of the IT or security team. In simple terms: Shadow AI = Unauthorized AI usage inside an organization. Now here is the bigger issue? Many organizations do not have an AI usage policy, let alone monitoring or even governance around how these tools are used. Employees are trying to be more productive but without guardrails, productivity can easily turn into data exposure. Shadow AI is quickly becoming the new Shadow IT except this time, the risks involve data privacy, intellectual property, and regulatory compliance. The question organizations should start asking is not: “Are employees using AI?” The real question is: “Do we know how they are using it, and what they are feeding it?" If your organization has not yet addressed AI governance, this is the time to start. -> Introduce clear policies. -> Employee awareness. -> Defined guardrails for safe AI use. Because the hidden AI inside your organization today could quietly become tomorrow’s data breach.

I recently asked a client to provide evidence of their vendor due diligence process and guess what.... There was no evidence that vendor assessments were being conducted. No proof, they had nothing, No Vendor Risk Assessment No Vendor Evaluation Report No Service Level Agreement That was how bad it was. The only document available was a vendor management policy stating that vendors should be assessed and evaluated. However, there was no evidence that these activities were actually being performed. This raises an important question: How do you know your vendors have adequate security controls in place if you have never verified them? Third-party relationships extend an organization’s attack surface. P.S: You don't just inherit a vendor's services, you inherit their vulnerabilities too. If your vendor is compromised, YOU are compromised. Supply chain attacks continue to grow in sophistication and impact. Incidents like the SolarWinds supply chain attack have already shown how a single compromised vendor can affect thousands of organizations. Attackers have figured out that targeting your trusted vendors is far easier than breaking down your front door. So ask yourself right now: → Do you know what security controls your vendors have in place? → Do you have evidence they actually FOLLOW them? → When did you last review your vendor risk register? If you're hesitating on any of those — this is your wake-up call. The bare minimum every organization should have is: -> Vendor Risk Assessment -> Vendor Evaluation Report -> Service Level Agreements with security clauses included -> Periodic vendor security reviews -> Evidence of compliance not just policy A policy is just a written document, it needs to be backed up with an evidence. We need to know the difference. We actually need to do better as organizations that hold the data of people. If this resonated with you, share it with a decision-maker who needs to see it.

@elormkdaniel This guy 😂😭. It's a new week please 🙏🏾

Some people in this space think not posting much automatically makes them “Cracked” so they throw subtle shades at those who share, post, ask questions, and contribute regularly. Let this be clear to you all: posting consistently doesn’t mean someone lacks real-world value. And staying quiet online doesn’t automatically make you an expert. You don’t know where people work, what they do behind the scenes, or the level of experience they have. So please drop the self-acclaimed superiority. It’s unnecessary. 🙂‍↔️

@elormkdaniel The amount of effort that goes into building online, studying, and still delivering at work is crazy….. Shout out to the people who keep showing up and putting in the work

@elormkdaniel Eiiiiii 😹😹 You want to start war
