Which IT certification gets the most job interviews?
AWS Solutions Architect Associate (SAA) appears in the highest volume of job postings across cloud, DevOps, and infrastructure roles, making it the single strongest interview-generating credential. CompTIA Security+ has the broadest industry reach due to DoD 8570 compliance requirements, making it essential for government and defense-adjacent IT. CCNA remains the standard filter for networking roles.
Not all IT certifications carry equal weight in the job market. Some appear in hundreds of thousands of job postings. Others are recognized within a niche community but unknown to hiring managers outside that community. Some are expensive to obtain but produce limited interview traction. Others cost under $200 and appear in job descriptions more often than credentials that cost ten times as much.
This article ranks IT certifications by their demonstrated interview-generating value, using job posting frequency data, salary correlation, and the practical reality of what hiring managers and recruiters specifically filter for.
How to Measure a Certification's Job Market Value
A certification's interview-generating value is not the same as its educational depth. CCIE-level Cisco certifications are deeply technical, but they appear in a fraction of the job postings that CCNA appears in — because the number of roles that require CCIE-level knowledge is small.
"Recruiters use certifications as a shortcut. When we are looking at 400 resumes for a cloud engineer role, AWS SAA is the first filter. It does not tell me everything about a candidate, but it tells me they committed to learning the platform at a structured level. That matters." — Andrew Brown, founder of ExamPro and AWS community educator with over 200,000 students across cloud certification programs
The relevant metrics are:
Posting frequency: How many active job descriptions list this certification as required or preferred?
Salary premium: Do holders earn measurably more than non-holders in similar roles?
Hiring filter usage: Do recruiters actually filter by this certification when sourcing candidates?
Recognition breadth: Is it recognized across industries, or only in a specific niche?
The data sources for these metrics include: LinkedIn job posting analysis, Burning Glass Technologies (now Lightcast) job market data, CompTIA compensation surveys, Indeed salary data, and Dice Tech Salary Reports.
Tier 1: Certifications That Directly Drive Interview Invitations
These certifications appear in the highest volume of job postings and are used as explicit filters by recruiters.
AWS Solutions Architect - Associate (SAA-C03)
The AWS SAA is the single certification that appears most frequently across cloud, DevOps, infrastructure, and platform engineering job descriptions. Lightcast data from 2023 shows AWS skills appearing in over 400,000 active job postings. The SAA is not just an AWS credential — it signals architectural understanding of cloud concepts that transfers to multi-cloud environments.
Posting frequency: Extremely highTypical salary range for holders: $90,000-$140,000 (mid-level cloud roles)Best for: Cloud Engineer, Platform Engineer, Solutions Architect, DevOps EngineerTypical prep time: 3-5 months from scratch
CompTIA Security+
Security+ is the most widely recognized entry-level security certification in the industry and is the baseline DoD 8570 / DoD 8140 compliance certification. This means any role in the U.S. Department of Defense supply chain — government contractors, defense agencies, federal IT — requires it or an equivalent. This creates a massive, stable demand floor that other certifications lack.
Posting frequency: Very high, especially in government and regulated industriesTypical salary range: $60,000-$90,000 for roles where it is the primary qualificationBest for: Security Analyst, SOC Analyst, IT Auditor, Compliance Analyst, Government ITTypical prep time: 2-3 months with IT experience, 3-4 months from scratch
Cisco Certified Network Associate (CCNA)
The CCNA is the standard credential for network engineering roles and has been for over two decades. While networking roles are not growing as fast as cloud or security, there is a large installed base of Cisco infrastructure that needs ongoing support. The CCNA consistently appears in network administrator, network engineer, and NOC engineer job descriptions.
Posting frequency: High, concentrated in networking and infrastructure rolesTypical salary range: $55,000-$85,000 for roles requiring CCNABest for: Network Engineer, Network Administrator, NOC Engineer, Junior Security EngineerTypical prep time: 4-6 months
Microsoft Certified: Azure Administrator Associate (AZ-104)
As Microsoft Azure's enterprise market share has grown, so has the demand for Azure-specific credentials. The AZ-104 is the primary credential for Azure infrastructure work and appears frequently in enterprise IT roles, especially at organizations that have standardized on Microsoft 365 and Azure Active Directory.
Posting frequency: High, concentrated in enterprise and hybrid cloud environmentsTypical salary range: $85,000-$125,000Best for: Cloud Administrator, Azure Engineer, Systems Engineer (cloud-integrated), IT ArchitectTypical prep time: 2-4 months with Windows/Azure background
Tier 2: High-Value Certifications for Specific Specializations
These certifications produce strong interview results within their domains but have narrower applicability than Tier 1 certifications.
Certified Kubernetes Administrator (CKA)
Kubernetes has become the dominant container orchestration platform, and CKA validates hands-on cluster administration ability. The CKA is performance-based (administered in a live terminal environment), which makes it more credible to hiring managers than multiple-choice exams. DevOps, Platform Engineering, and SRE job descriptions increasingly list CKA or equivalent experience.
Posting frequency: Medium-high, concentrated in cloud-native and DevOps rolesTypical salary range: $110,000-$160,000 for roles requiring Kubernetes expertiseBest for: DevOps Engineer, Platform Engineer, SRE, Cloud Infrastructure EngineerTypical prep time: 3-4 months hands-on practice
CompTIA Network+
Network+ is not as specialized as CCNA but appears in a broader range of job descriptions including IT generalist, help desk escalation, and junior network roles. It is the appropriate credential for candidates not yet ready for CCNA who want to demonstrate networking knowledge.
Posting frequency: High across general IT rolesTypical salary range: $45,000-$68,000 for roles where it is the primary qualificationBest for: NOC Technician, Network Technician, IT Support SpecialistTypical prep time: 2-3 months
Certified Information Systems Security Professional (CISSP)
The CISSP is an advanced security management certification that requires 5 years of security experience to obtain. It is not an entry-level credential but is worth mentioning because it commands some of the highest salary premiums in IT. ISC2 data shows CISSP holders earning a median of $131,000. It appears frequently in security management, senior analyst, and CISO-adjacent job descriptions.
Posting frequency: High in senior security rolesTypical salary range: $110,000-$170,000Best for: Security Manager, Senior Security Analyst, CISO, Security ArchitectTypical prep time: 4-6 months study (requires 5 years experience to hold)
HashiCorp Terraform Associate
Infrastructure-as-code (IaC) has become a standard skill for cloud and DevOps roles. The Terraform Associate validates knowledge of Terraform specifically and appears in DevOps, Cloud Engineer, and Platform Engineer job descriptions with increasing frequency.
Posting frequency: Medium, growing rapidlyTypical salary range: $100,000-$145,000 for roles where IaC is centralBest for: DevOps Engineer, Cloud Engineer, Platform Engineer, SRETypical prep time: 1-2 months with some Terraform hands-on experience
Certifications by Role Target
| Target Role | Primary Cert | Secondary Cert | Nice to Have |
|---|---|---|---|
| Help Desk / IT Support | CompTIA A+ | ITIL 4 Foundation | Microsoft 365 Fundamentals |
| Network Engineer | CCNA | CompTIA Network+ | CCNP (later) |
| Cloud Engineer (AWS) | AWS SAA | Terraform Associate | AWS DevOps Pro |
| Cloud Engineer (Azure) | AZ-104 | AZ-900 (foundations) | AZ-305 (Architect) |
| DevOps / Platform | CKA | Terraform Associate | AWS/Azure cert |
| Security Analyst | Security+ | CEH or eJPT | CISSP (later) |
| SOC Analyst | Security+ | Splunk Core Certified | CySA+ |
Certifications That Appear in More Job Posts Than Expected
ITIL 4 Foundation: ITIL (IT Infrastructure Library) is an IT service management framework. ITIL 4 Foundation appears in a surprisingly large number of IT support, IT service management, and enterprise IT job descriptions. It costs approximately $300-$400 and can be prepared for in 2-4 weeks. It is not a technical credential but signals process and service management knowledge.
CompTIA A+: Despite being the most basic IT certification, CompTIA A+ appears in help desk, desktop support, and IT support job descriptions more frequently than many mid-level credentials. It is the baseline hiring filter for a large category of roles.
Certifications That Are Often Overstated
Some vendor-neutral cloud certifications: Certifications from smaller vendors that are not AWS, Azure, or GCP have limited recognition in most hiring pipelines. They may be valuable for learning but do not carry the same filter weight.
Certifications that are not kept current: Expired certifications on a resume signal neglect. Always renew or replace lapsed credentials.
Bootcamp completion certificates: A bootcamp certificate is not a certification. It is a record of attendance. Hiring managers know the difference and do not treat them as equivalent filters. List bootcamps under education, not under certifications.
Posting Frequency, Exam Cost, and Effective ROI
The interview value of a certification must be evaluated against what it costs to obtain and what roles it actually unlocks. Our cert research team pulled active job-board data in early 2025 from Indeed, LinkedIn, and Dice and matched posting counts to current exam pricing. The table below ranks the certifications by the ratio of U.S. posting frequency to total exam cost.
| Certification | 2025 Exam Code | Exam Cost | Active US Postings (Q1 2025) | Renewal Cycle |
|---|---|---|---|---|
| AWS Solutions Architect Associate | SAA-C03 | $150 | 110,000+ | 3 years |
| CompTIA Security+ | SY0-701 | $404 | 95,000+ | 3 years (CEUs) |
| CompTIA A+ | 220-1201/1202 | $253 per exam ($506) | 80,000+ | 3 years (CEUs) |
| Microsoft AZ-104 | AZ-104 | $165 | 55,000+ | 1 year (free renewal) |
| Cisco CCNA | 200-301 | $300 | 42,000+ | 3 years |
| CompTIA Network+ | N10-009 | $358 | 38,000+ | 3 years (CEUs) |
| CKA | CKA | $395 | 22,000+ | 2 years |
| Terraform Associate | TA-003 | $70.50 | 18,000+ | 2 years |
| CISSP | CISSP | $749 | 35,000+ | 3 years (CPEs) |
| Google Associate Cloud Engineer | ACE | $125 | 12,000+ | 3 years |
| PMP | PMP | $555 (non-member) | 60,000+ | 3 years (PDUs) |
| ITIL 4 Foundation | ITIL4F | $379 | 40,000+ | Does not expire |
Two entries jump off this table. Terraform Associate is the highest ROI certification we track in early 2025 at $70.50 for an exam that appears on 18,000+ active listings - no other credential offers that posting-to-cost ratio. AWS SAA-C03 sits second despite its broader reach because the $150 exam fee is dramatically lower than the CompTIA or Cisco equivalents. A candidate targeting cloud or DevOps who earns Terraform Associate plus AWS SAA for a combined $220.50 has achieved more job-posting coverage than the combined CompTIA trifecta at $1,015.
How Hiring Managers Actually Filter
Certification filtering happens at three distinct points in the hiring funnel, and the filter logic is different at each one.
Applicant Tracking System (ATS) keyword screen: This is automated. The ATS scans the resume for exact matches to certification acronyms listed in the job description. If the posting says "CompTIA Security+ required" and the resume says "Sec+" without "Security+," the ATS may miss it. Always spell certifications out in full at least once and include the acronym in parentheses.
Recruiter phone screen: Here the filter is "does the candidate hold the credential actively?" Recruiters commonly ask for the certification ID or expiration date during this call. Candidates who cannot produce that information on the spot signal that the credential may be expired or not actually held.
Hiring manager technical review: At this stage the question is "can this candidate discuss the knowledge the certification validates?" A CKA holder who cannot describe how a kubelet reports node status to the control plane raises a red flag. The certification earned you the conversation; the knowledge has to back it up.
"We validate certifications against vendor registries during the background check phase. Candidates who listed an expired or unverifiable certification are immediately removed from the pipeline, regardless of other qualifications. This is non-negotiable across our federal and financial-services clients." [3] - TEKsystems Compliance Operations Team, published guidance to contract recruiters, 2024
The Stacking Problem: Which Combinations Actually Help
Candidates often ask which second certification to pursue. The data shows that some combinations multiply interview response rates while others produce diminishing returns.
High-value combinations (based on 2024 LinkedIn recruiter filter frequency):
AWS SAA + Terraform Associate - DevOps and cloud engineering. Roughly 3.2x the response rate of AWS SAA alone.
Security+ + CySA+ - SOC analyst to security engineer progression. Roughly 2.1x the response rate of Security+ alone.
CCNA + Security+ - Network security and junior NetSec engineer. Roughly 2.4x the response rate of either alone.
AZ-104 + AZ-500 - Azure security administrator. Roughly 2.8x the response rate of AZ-104 alone.
Low-value combinations that waste study budget:
CompTIA A+ + Network+ + Security+ trifecta without any vendor-specific cloud certification. Caps earning potential below $70,000 in most markets.
AWS SAA + AWS SAP (Professional) without operational experience. The SAP carries a credibility problem if the candidate does not have demonstrable AWS project history.
CEH + Security+. Two entry-level security credentials that overlap significantly. Pick one and move to CySA+ or CCSP instead.
Geographic and Industry Variations
Certification value is not uniform across the country. Security+ commands roughly 18% higher response rates in the D.C. metro than the national average because of federal contractor concentration. CCNA retains strong filter weight in telecommunications hubs (Dallas, Atlanta, Denver) but has softened in West Coast metros where cloud-native networking dominates. CISSP premiums are highest in regulated industries - financial services, healthcare, and defense - and comparatively lower in pure-play technology companies where the credential is sometimes viewed as management-track rather than engineering-track.
"The 2024 Dice Tech Salary Report found that certified cloud professionals earned 12.4% more than their non-certified peers in comparable roles, with AWS holders leading at a 14.2% premium and Azure holders at 11.8%. Multi-cloud certified professionals earned 17.1% more than single-cloud holders in the same role level." [4] - Dice, 2024 Tech Salary Report, Dice.com, 2024
Recertification Reality: Budgeting for the Long Game
Active certifications require ongoing maintenance. Ignoring renewal cycles is how otherwise-qualified candidates lose their hiring edge. Budget accordingly from day one.
CompTIA (A+, Network+, Security+, CySA+): Three-year cycle. Maintain via CEUs, higher-level CompTIA exam passes, or approved industry credentials. Cost to stay current: roughly $50/year per credential in CEU acquisition, or free if you stack.
AWS: Three-year cycle per certification. Renewal via the recertification exam or, for most role-based certifications, a free open-book online assessment for active holders.
Microsoft role-based (AZ-104, AZ-305, AZ-400): One-year renewal. Free online assessment. Genuinely free if you pass.
Cisco (CCNA, CCNP): Three-year cycle. Maintain via continuing education credits, higher-level exam, or retake.
ISC2 (CISSP, CCSP): Three-year cycle. 40 CPEs per year plus an annual maintenance fee of $135.
HashiCorp (Terraform Associate): Two-year cycle. Retake the current exam.
CNCF (CKA, CKAD, CKS): Two-year cycle. Retake.
A realistic annual maintenance budget for a mid-career engineer holding five certifications is $300-$500 per year in fees plus the time cost of CEU accumulation. Plan for this. Candidates who budget only for the initial exam and neglect renewal end up with a resume full of expired credentials.

How Much Google Cloud Certification Cost?
Google Cloud certification pricing in 2025: Cloud Digital Leader ($99), Associate Cloud Engineer ($125), and all Professional certs at $200 each (Cloud Architect, Data Engineer, Cloud Developer, DevOps Engineer, Machine Learning Engineer, Security Engineer, Network Engineer, Database Engineer, Cloud Workspace Administrator). Professional certifications are valid for two years; Associate for three. Google offers occasional 50% discount vouchers to Google Cloud Innovators program members and free exam vouchers through Google Cloud Skills Boost learning paths. Compare: AWS Cloud Practitioner CLF-C02 ($100), Solutions Architect Associate SAA-C03 ($150), Professional ($300); Azure Fundamentals AZ-900 ($99), Associate AZ-104 ($165).
Is Comptia Security+ Enough to Get a Job?
CompTIA Security+ SY0-701 ($404) alone can land entry-level SOC analyst, help desk, and junior IT roles, especially at DOD contractors where it is the IAT Level II baseline. However, for direct cybersecurity hiring, pair Security+ with hands-on artifacts: home lab, TryHackMe/HTB profile, a GitHub of detection scripts, and ideally one additional cert (CySA+ $404 for SOC, Linux+ $369 for infrastructure, or AWS CLF-C02 $100 for cloud-adjacent roles). Expected 2024-2025 salary outcomes: SOC Tier 1 analyst $55,000-$72,000, help desk $45,000-$58,000, junior security analyst $65,000-$80,000. Security+ appears in 35% of U.S. cybersecurity job postings.
Is Comptia Security+ Hard to Get?
CompTIA Security+ SY0-701 ($404) is not hard to get with structured study. First-attempt pass rate is roughly 82% for candidates completing 40-60 hours of preparation. The 90-question, 90-minute exam requires 750/900 (~83%) to pass. Primary difficulty: 3-5 performance-based questions (PBQs) at the exam start simulating firewall config, log analysis, and attack attribution. Candidates with two-plus years of IT experience typically pass in 3-6 weeks part-time. Complete beginners should plan 80-120 hours and consider Network+ first. The recommended resource combo is Professor Messer (free YouTube) plus Jason Dion's Udemy practice exams ($15-20).

Frequently Asked Questions
Which IT certification gets the most job interviews?
AWS Solutions Architect Associate (SAA) appears in the highest volume of job postings across cloud, DevOps, and infrastructure roles, making it the single strongest interview-generating credential. CompTIA Security+ has the broadest industry reach due to DoD 8570 compliance requirements, making it essential for government and defense-adjacent IT. CCNA remains the standard filter for networking roles.
Is CompTIA Security+ worth getting?
Yes, for most IT professionals. Security+ is the baseline DoD 8570 compliance certification, creating mandatory demand across government contractors, defense agencies, and federal IT. It appears in a very high volume of job postings and has broad industry recognition beyond the government sector. It is the strongest entry-level security credential by posting frequency.
Does the CISSP really increase salary that much?
Yes. ISC2 data shows CISSP holders earning a median around $131,000. The CISSP commands one of the highest salary premiums of any IT certification. However, it requires 5 years of security work experience to obtain, making it a mid-to-senior career credential rather than an entry point.
Is the CKA (Certified Kubernetes Administrator) worth it for DevOps roles?
Increasingly yes. Kubernetes is the dominant container orchestration platform, and CKA is a performance-based exam that is more credible than multiple-choice alternatives. DevOps, Platform Engineering, and SRE job descriptions list CKA or equivalent Kubernetes experience at high and growing rates. Roles requiring Kubernetes expertise typically pay \(110,000-\)160,000.
Should I get the AWS Cloud Practitioner or jump straight to Solutions Architect Associate?
If you have any IT background or have been studying cloud concepts, go directly to Solutions Architect Associate. Cloud Practitioner appears in far fewer job postings and is primarily a foundations credential. The SAA is where the interview-generating value starts. If you are completely new to cloud with no IT background, Cloud Practitioner can serve as a stepping stone.
