To HR managers and hiring systems, certifications provide instant filters and credibility. Cybersecurity roles grew so fast that employers needed simple screening tools. As one analysis notes, with millions of unfilled jobs looming, certifications gave recruiters “an easy way to screen applicants for infosec jobs”. In practice, many Applicant Tracking Systems (ATS) are programmed to spot cert keywords (e.g. CISSP, OSCP, Security+) and boost those resumes. A certificate reassures employers that a candidate has at least covered an industry-standard curriculum.
By 2025, the cybersecurity battlefield is evolving fast, and the hottest skills reflect emerging threats and technologies. Employers report growing demand for capabilities across cloud, network, and data security, as well as automation. Key technical skills employers seek include:
1. Network Security & Firewalls: Deep knowledge of firewalls (including next-generation firewalls), routers, VPNs and troubleshooting remains core. Skills in configuring and managing Ethernet networks and routing protocols (e.g. OSPF, BGP) are essential.
2. Cloud Security: Protecting AWS, Azure or Google Cloud platforms is critical. Cloud skills earned a high premium – one report notes cloud expertise can boost salary by – because nearly 40% of organizations lack adequate cloud security personnel. Employers want engineers who can secure containers, identity, and data in cloud environments.
3. Threat Detection & Incident Response: Proficiency with SIEM tools, intrusion detection/prevention (IDS/IPS), and log analysis is in high demand. Incident response know-how including digital forensics and malware analysis – is crucial for containing attacks quickly. Skills like threat hunting and intrusion analysis, often practiced in CTF challenges, directly appeal to employers.
5. Cryptography and Data Protection: Understanding encryption, key management and secure protocols is sought after. Employers also prize familiarity with data privacy standards and compliance (e.g. GDPR, HIPAA).
6. DevSecOps and Automation: Integrating security into the DevOps process (DevSecOps) is a growing focus. Skills with CI/CD pipelines and automation/orchestration platforms (e.g. Kubernetes security, SOAR tools) are increasingly requested. Approximately 10% of cybersecurity job postings now explicitly require AI/automation skills, reflecting the rise of AI-driven tools and machine learning for security.
NG Networks’ own analysis similarly lists firewalls, troubleshooting networks, router management and broad cybersecurity fundamentals as must-haves. In short, technical breadth plus depth is required.
This “skills gap” arises because infosec is hands-on by nature. Reading about XSS or SQL injection isn’t the same as exploiting them in a lab. Candidates who’ve only ticked off certification checklists often falter in technical interviews. Employer interviewers routinely note that theory-heavy candidates can’t clearly describe how they would isolate a compromised host or decode encrypted traffic. At NG Networks we follow a structured approach as we train our students first about Networking then Network Security and later about Cybersecurity. All the stages include regular mock tests, real time training along with practical learning of every concept in the labs. In other words, a certificate shows you know something, but a skillful candidate proves they can do it.
Because of this gap, companies will still hire trainable juniors rather than “unicorns.” CISOs report hiring as their top challenge, partly because unrealistic requirements chase away candidates. An entry-level posting asking for 3+ years of experience eliminates many good prospects. After all, tools and threats evolve quickly; it’s more important to learn how to learn than to know last year’s buzzwords.
How to Build Cybersecurity Skills
2. Use Online Learning Platforms: Once Engage with guided practice on platforms like TryHackMe or Hack The Box. These sites offer progressive “learn paths” and CTF (Capture The Flag) challenges that simulate real vulnerabilities. Completing rooms teaches concepts and gives you credentials to showcase. For example, report write-ups on GitHub or platform badges earned. Cybersecurity veterans say solving even a few beginner CTFs is more impressive than a dozen certificates, because it proves problem-solving under the hood.
4. Work on Real Projects: Seek internships, volunteer work or freelance gigs. You don’t need a “cyber” title to start, even an IT support or helpdesk role can evolve into security tasks. The key is getting your hands dirty. These experiences count on your resume. Likewise, participating in bug bounty programs.
5. Contribute to Open-Source & Write About It: Another way to demonstrate initiative is to take on community projects. For instance, volunteer to harden an open-source project. Even writing a blog post about the security measures you implemented can highlight your knowledge.
6. Practice Regularly and Learn from Others: Cybersecurity is vast; make continuous learning a habit. Participate in Hackathons, cyber clubs or online communities (Discord, Slack, Reddit r/netsec, etc.) to exchange knowledge. Try NG Networks’ recommended “Learning Path” programs, Podcasts or virtual webinars. Follow industry news and experiment with new tools (e.g. sniffing Wireshark packets, writing a simple scanner in Python, using Splunk/ELK to search logs). Over time, these cumulative experiences build “real-world” understanding that no exam can substitute
- Fundamental Networking & Security: You must be comfortable with TCP/IP networks, Ethernet, routers and switches. Knowing how to configure a firewall, VPN or VLAN is basic table stakes. Troubleshooting network connectivity issues is also key.
- Systems & OS Proficiency: Be fluent with at least one server OS (Linux/Windows) and their command lines. Understand system hardening, logs, user permissions and services.
- Cloud Platforms: AWS, Azure or GCP skills would be really helpful. Gain experience configuring cloud VMs, storage and IAM policies, and securing cloud resources (for instance, AWS Certified Security – Specialty builds these competencies).
- Security Tools & Processes: Hands-on use of security technologies is expected. This includes SIEM log monitoring, IDS/IPS, endpoint protection, VPNs, encryption tools and vulnerability scanners. Know at least one packet analyzer (Wireshark), one pen-test framework (Metasploit, Burp), and one forensics toolchain.
- Threat Detection & Response: Skill in analyzing alerts and investigating incidents is a differentiator. You should understand the basic incident response process (contain, eradicate, recover) and have practiced live-fire exercises.
- Cyber Defense Concepts: Topics like identity/access management (IAM), public-key cryptography, and security architecture (e.g. zero-trust networks) should be in your toolkit. Stay updated with the evolving threats like ransomware tactics, supply chain attacks, and AI-driven attacks.
- Soft Skills & Problem Solving: Communication, teamwork and analytical thinking are indispensable. You’ll often explain technical risks to non-experts or work in cross-functional teams.
- Adaptability & Continuous Learning: Security changes daily. Show initiative by quickly learning new platforms (e.g. DevSecOps tools) and adapting to business needs. On-the-job learning (through mentorship or labs) should be a constant.
