Chirag has spent almost 15 years in cybersecurity and worked in 10 different countries with talented cyber engineers. So, he knows the difference between a virus and a worm. 

Early in his career, he provided network security for Fortune 500 clients before advancing to cybersecurity, where he then spent his time learning and securing multiple clouds. His journey led him to Australia, where he worked with the government before starting his company and consulting for South Australia Health Department and a major bank. He won several prestigious awards and earned around 26 technical certifications.

VPNs may look similar from the outside, but each type works differently and offers different levels of security.

🔐 IPSec VPN

Enterprise grade, highly secure, and ideal for site to site connections.

Encrypts traffic at the network layer and is commonly used for connecting branch offices or data centers.

🌐 L2TP over IPSec

L2TP alone is not secure, but when paired with IPSec it becomes a reliable tunnel for remote users.

Still found in some legacy or mixed environments.

⚠️ PPTP VPN

Fast but outdated and considered insecure today.

Uses weak encryption and should not be used in any business setup.

🧩 SSL VPN

Modern, user friendly, and works over HTTPS, which makes it perfect for remote workers.

Allows controlled access to specific internal apps instead of exposing the entire network.
Choosing the right VPN depends on what your organisation needs: security level, performance, and how much access users should get.

If you need help setting up secure VPN connections or reviewing your remote work architecture, Cybernara can support you.

When most people hear the word “hacker,” they instantly think of cybercriminals — the ones breaking into systems and stealing data.

But in the world of cybersecurity, not all hackers are villains.
Hackers come in different “hats,” each representing their intent, ethics, and skill level.

🕶️ Black Hat — The classic “bad guys.”

They exploit vulnerabilities for personal gain using methods like malware, ransomware, or DDoS attacks.

🤍 White Hat — The ethical defenders.

They work to find and fix vulnerabilities through penetration testing and security audits — often helping organizations stay safe.

⚫ Gray Hat — The blurry middle ground.

They expose flaws without permission — not always with malicious intent, but still crossing ethical lines.

💚 Green Hat — The curious beginners.

New to hacking, they experiment with tools and scripts, often learning through online communities and forums.

💙 Blue Hat — The avengers.

They hack for personal revenge or retaliation, using doxxing or site defacement — typically driven by emotion, not profit.

❤️ Red Hat — The vigilantes.

They target Black Hat hackers directly, launching aggressive counter-attacks — sometimes as extreme as the hackers they fight.

🎯 The takeaway:

Understanding hacker types helps organizations identify threats, predict behaviors, and build stronger defenses.

Not all hackers are enemies — some are the first line of defense in a digital war fought silently every day.

💡 At Cybernara, we simplify cybersecurity — making complex topics clear, visual, and actionable.

🛡️ Penetration testing isn’t guesswork — it’s a craft built on the right tools.

From network scanning to web app exploitation to reverse engineering, each phase of a real assessment depends on a different skillset… and a different toolkit.

That’s why security teams rely on a mix of proven, battle-tested tools like:

• Metasploit for exploitation
• Burp Suite and OWASP ZAP for web app testing
• Nmap and Wireshark for network discovery and traffic analysis
• SQLMap, WPScan, and Acunetix for targeted vulnerability detection
• John the Ripper and Aircrack-NG for password and wireless testing
• IDA Pro, Kali Linux, BeEF, and others for deeper, specialized work

Each tool uncovers a different layer of weakness — and together, they expose the gaps attackers love to exploit.

🔐 At Cybernara, these aren’t just names on a list.

They’re part of our daily toolkit for delivering thorough, professional penetration tests across applications, cloud, networks, and infrastructure.

If your business needs a real security assessment — not a surface-level scan — we can help.

🔐 Active Directory remains a prime target for attackers — but securing it doesn’t have to be overwhelming.

Here’s a 12-step AD Security Checklist to harden your environment:

✅ Strong password policies

✅ MFA for all privileged accounts

✅ Least privilege & RBAC

✅ Secure admin accounts

✅ Continuous monitoring & audits

⚡ The shift: Modern AD security isn’t just about passwords — it’s about layered defense, proactive monitoring, and zero trust principles.

💡 At Cybernara, we help organizations strengthen their identity and access management with compliance-driven, threat-informed strategies.

Let’s connect if you want to lock down your AD before attackers try to break in.
