What Does a Cybersecurity Analyst Do — and Will AI Replace Them?

A cybersecurity analyst will not be replaced by AI anytime soon, but the job is changing fast. AI now handles a growing share of routine threat detection, which is pushing analysts toward higher-judgment work: investigating incidents, closing gaps attackers actually exploit, and making the calls that automated systems aren't trusted to make alone.

Quick facts: AI Impact: Moderate · Salary: US median $124,910/year · Education: Bachelor's degree (typically Computer Science or Information Security) · Core skills: threat detection, incident response, SIEM tools.

What Does a Cybersecurity Analyst Do?

A cybersecurity analyst monitors an organization's networks and systems for signs of intrusion, then investigates and contains whatever they find. The daily work includes reviewing alerts from security tools, patching known vulnerabilities before attackers exploit them, and running or contributing to incident response when something does go wrong.

Analysts also spend real time on unglamorous but essential tasks: writing security policies, running phishing simulations, and briefing non-technical stakeholders on risk. The role sits at the intersection of technical depth and organizational judgment, which is exactly why AI can absorb parts of it without replacing the person doing it.

How Is AI Changing Cybersecurity Analysis?

AI has already taken over a meaningful chunk of the detection layer. Machine learning models built into modern SIEM and XDR platforms flag anomalies, correlate alerts across thousands of log sources, and triage low-priority noise. This is work that used to consume hours of an analyst's day. Tools like Microsoft Copilot for Security and CrowdStrike Charlotte AI can summarize an incident timeline or draft a first-pass investigation in minutes.

What AI still struggles with is context and accountability. Deciding whether an anomaly is a genuine breach or a false positive often requires knowledge of how a specific business operates, which systems actually matter, and what an acceptable risk tradeoff looks like for that organization. AI-generated recommendations still need a human to weigh legal exposure, business impact, and reputational risk before acting. Someone has to be answerable when a decision goes wrong, and that accountability doesn't transfer to a model.

"The tools got faster, but somebody still has to decide what the alert actually means for this business, and own that call." That's a common refrain among senior analysts adapting their teams to AI-assisted workflows.

The role is shifting from manual alert-chasing toward AI supervision and higher-order investigation. In three to five years, expect entry-level analysts to spend less time triaging raw logs and more time validating AI output, tuning detection models, and handling the incidents that require genuine judgment. Analysts who learn to direct AI tools well will likely handle a wider scope of responsibility than before, not a narrower one.

Which Skills Will Still Matter?

• Incident response and forensics: the human-led work of containing and explaining a breach after AI flags it
• Security architecture and risk assessment: designing systems and evaluating tradeoffs AI can't own
• Cloud security: as more infrastructure moves to AWS, Azure, and GCP, cloud-specific expertise is increasingly non-negotiable
• Communication: translating technical risk into decisions executives and boards can act on

A degree in Computer Science, Information Security, or a related Cybersecurity program remains the most common entry path, paired with certifications like CompTIA Security+ or CISSP once in the field.

Career Outlook

Cybersecurity remains one of the fastest-growing tech careers. In the US, employment of information security analysts is projected to grow 29% from 2024 to 2034, far outpacing the average for all occupations, with about 16,000 openings projected annually. The median annual wage was $124,910 as of May 2024, with the top 10% earning over $186,000.

Demand isn't limited to the US. Every APAC market in this guide is investing heavily in cyber talent as digital infrastructure and financial services expand, which is opening up real opportunities for analysts willing to study or work abroad.

Study and Work Abroad

Study Abroad

Several APAC destinations offer strong cybersecurity programs with a clear path to local work after graduation:

1. Australia: Edith Cowan University is recognized as an Academic Centre of Cyber Security Excellence, and graduates can apply for the Temporary Graduate visa (subclass 485) for post-study work rights.
2. Singapore: National University of Singapore runs one of the region's most respected cybersecurity programs, backed by Singapore's aggressive push to become a regional cyber hub.
3. Taiwan: National Yang Ming Chiao Tung University has a strong information security research track, relevant given Taiwan's semiconductor sector's growing cybersecurity needs.

Work Abroad

For analysts ready to work internationally, a few markets stand out:

• Australia pays competitively and has a persistent cybersecurity skills shortage; firms like Telstra run large in-house security operations centers and regularly sponsor skilled visas.
• Singapore offers strong salaries and hosts regional security hubs for major firms, with GovTech Singapore among the notable employers driving national cyber initiatives; the Employment Pass is the standard route in.
• Hong Kong has growing demand tied to its financial sector, where firms like HKT maintain sizeable security teams, and the General Employment Policy visa covers most skilled hires.

FAQs

Will AI replace cybersecurity analysts?

No. AI is automating detection and triage, but analysts are still needed for incident response, risk judgment, and accountability, work that keeps shifting toward higher-value tasks rather than disappearing.

Is cybersecurity analyst a good career to get into right now?

Yes. Demand remains strong, with the US projecting 29% job growth through 2034, and AI is increasing the volume of threats organizations face rather than reducing the need for skilled analysts.

Do cybersecurity analysts need to know how to code?

Not always at entry level, but scripting languages like Python help with automating repetitive tasks, and coding knowledge becomes more valuable as analysts move into senior or specialized roles.

Is cybersecurity analyst an entry-level job, or do I need experience first?

Some entry-level and apprenticeship paths exist, but most employers prefer candidates with a relevant degree or certification like CompTIA Security+ before hiring into the role directly.

Conclusion

Cybersecurity analysts aren't being replaced by AI; they're being handed better tools and higher expectations. The most useful next step is picking one high-leverage skill, like cloud security or incident response, and building toward it deliberately.
