How to Build Threat Detection Tools That Sell: Lessons from Ethical Hacking and Cybersecurity

The Best Defense Is a Good Offense, Built With the Best Tools

In cybersecurity, threat detection isn’t just about stopping attacks – it’s about creating tools security teams actually want to use. Think of it like rare coin collecting: the most valuable solutions combine functionality with market appeal. Here’s how to build cybersecurity tools that detect threats and win customers.

Understand the Market: What Moves in Cybersecurity?

Just like coin dealers track market trends, cybersecurity developers need to know which threats matter most. These are the ones worth detecting:

• Certified Threats – Verified indicators with minimal false positives, similar to professionally graded coins
• Zero-Day Vulnerabilities – The rare finds that make security teams take notice
• Common Exploits – Frequent but dangerous, like Log4j – they may not be rare but always have value

Building Smarter Detection

Here’s how you might prioritize threats in your detection system:

# Pseudocode: Threat Scoring Model
def score_threat(ioc):
if ioc.certified_by_pcgs_or_cac:
return 100 # Maximum confidence
elif ioc.is_zero_day:
return 90 # Rare but unverified
else:
return ioc.cvss_score * 10 # Common but still valuable

Pricing Your Tools: Know Your Worth

Seasoned coin collectors know – if something’s valuable, don’t give it away. The same goes for cybersecurity tools:

• Avoid the Freemium Trap – Free plans attract lookers, not buyers. Try time-limited trials instead
• Charge for Protection – With breaches costing millions, a tool that prevents them is easily worth six figures

Example: Selling Security Outcomes

Rather than billing by the hour, sell results: “We’ll find critical vulnerabilities or you don’t pay.” It’s like offering a money-back guarantee on a rare coin purchase.

Secure Coding: Protect Your Work

Just as collectors watch for counterfeit coins, developers must guard against malicious code:

• Validate Everything – Treat user input like an unknown USB drive found in the parking lot
• Check Your Dependencies – That free library might cost you more than you think

# Python: Safe Deserialization
import pickle

def safe_deserialize(data):
if not validate_signature(data):
raise ValueError("Untrusted source—possible exploit!")
return pickle.loads(data)

Make Your SIEM Work Like a Sales Floor

A good security dashboard should make important threats stand out:

• Create a “Bargain Bin” – Separate lower-priority alerts but keep them accessible
• Spot the Rarities – Use anomaly detection to highlight unusual attack patterns

Example: Finding Hidden Threats

# Kibana Query: Find "Key Date" Threats
event.dataset: "firewall" AND threat.indicator.confidence: "high"
AND threat.indicator.rarity: "<5_observed_globally"

Build to Win

Creating successful security tools requires three things:

• Focus on detecting what matters most
• Charge what your protection is worth
• Write code as secure as a vault

Build something that makes both attackers nervous and security teams eager to buy. That's when you know you've struck gold.
