Comparisons
Which approach fits? Honest comparisons, including when the other one is better.
Security budgets are finite. These pages compare testing approaches and regulations side by side and say clearly which one to choose in which situation.
In short
Zyberum compares security testing approaches and regulations pairwise: penetration test against vulnerability scan, red team and bug bounty, black box against white box, internal against external testing, manual against automated testing, and NIS2 against the Cyber Resilience Act. Each comparison states when which option is the better choice.
All comparisons
Side by side
Black Box vs White Box Penetration Test: How Much Should the Tester Know?
A black box test starts with no information, a white box test with code, documentation and accounts. What each finds and costs, and why grey box usually wins.
ComplianceIEC 62443 vs ISO 27001: Plant Security or Information Security Management?
ISO 27001 certifies an organisation's security management system. IEC 62443 secures industrial automation, from plant to PLC. Where they overlap and who needs which.
Penetration testingInternal vs External Penetration Test: Which Attacker Are You Simulating?
An external pentest attacks what the internet can reach. An internal one starts inside, as a phished employee would. What each finds and when you need which.
ComplianceISO/SAE 21434 vs IEC 62443: Vehicle or Plant, and What If Your Product Is Both?
ISO/SAE 21434 covers cybersecurity engineering for vehicles and ECUs, IEC 62443 covers industrial automation. Differences, overlaps and products that sit in between.
Detection and responseManaged SOC vs In-House SOC: Buy 24/7 Detection or Build It Yourself?
A managed SOC gives you 24/7 detection and response for a monthly fee. An in-house SOC gives control and context at the price of a team. Who should pick which, honestly.
Penetration testingManual vs Automated Penetration Testing: What Tools Find and What People Find
Automated tools find known weaknesses fast and repeatably. Manual testers find logic flaws, chains and anything new. Where the line runs and how to combine both.
ComplianceNIS2 vs Cyber Resilience Act: Which One Applies to You, and What Each Demands
NIS2 regulates operators of essential services; the CRA regulates products with digital elements. Who falls under which, duties, deadlines and penalties side by side.
Penetration testingPenetration Test vs Bug Bounty: Paid Days or Paid Findings?
A pentest buys tester time with a fixed scope and a full report. A bug bounty pays independent researchers per valid finding, with no end date. When each pays off.
Penetration testingPenetration Test vs Red Team: Scope, Goals and Which One You Need
A pentest finds as many vulnerabilities as possible in a defined scope. A red team checks whether detection and response stop a realistic attacker. Which fits when.
Penetration testingPenetration Test vs Vulnerability Scan: What Each Finds and When to Use Which
A vulnerability scan finds known weaknesses automatically; a penetration test finds what a scanner cannot. Differences in depth and cost, and when to use which.
How we compare
The same questions for every pair
Every comparison answers the same questions: what each approach finds, what it misses, what it costs, how long it takes, and which regulation or standard asks for it. Then it names the situations in which one option is clearly better, including the ones where you do not need us.
Prices are typical market ranges for Germany and the EU, not an offer. For your case you get a fixed price after a short scoping call.
