Engineering vs. PR
The surgeon, not the salesperson
Traditional agencies treat reputation on the surface. We treat its root cause: code, networks, data and evidence.
Approach
Traditional PR / ORM agency: Content writing and suppression SEO
DataSentinel: OSINT, forensics, cryptography and DevSecOps
Diagnosis
Traditional PR / ORM agency: Manual Google search
DataSentinel: Correlation of 1,200+ sources, breaches and dark web
Harmful content
Traditional PR / ORM agency: Buried under positive articles
DataSentinel: Removed at the source: host, registrar, legal action
Bot & DDoS attacks
Traditional PR / ORM agency: Out of scope
DataSentinel: WAF, L7 rules, anti-scraping in production
Data breach
Traditional PR / ORM agency: Crisis communication only
DataSentinel: Attack vector identified, closed, documented
Deliverable
Traditional PR / ORM agency: Slides and promises
DataSentinel: Evidence, logs, legal file, hardened systems
Point of contact
Traditional PR / ORM agency: Account manager
DataSentinel: The senior engineer handling your case
Technical rigour
Every action is measured, reproducible and documented.
Neutralisation at the source
We remove the cause, not just the symptom.
Absolute confidentiality
NDA, end-to-end encryption, minimal data retention.
Expertise
20 years of engineering at the service of your security

FAQ
Frequently asked questions
How does the instant audit work?
You enter a name, domain, email or brand. Our pipeline queries over 1,200 open sources, breach databases and dark web channels, then an LLM classifies the tone and risk of each finding. The PDF report is generated in minutes, with evidence and a prioritised remediation plan.
Is the audit legal?
Yes. We only use publicly accessible sources and leak databases indexed for defensive purposes. You confirm at checkout that you are authorised to audit the target (yourself, your company or a principal who has mandated you).
Can you really remove content from the internet?
When content is illegal, defamatory, infringes copyright or exposes personal data, we file legal-technical requests (GDPR, DMCA, Right to be Forgotten, platform policies) with hosts, registrars and search engines. Each case is assessed up front; we never promise what the law does not allow.
How fast do you respond to an incident?
The emergency line is staffed 24/7/365. Triage starts within 15 minutes and an engineer is engaged on your systems in under 2 hours.
How is my data protected?
An NDA is signed before any sensitive exchange. Data is encrypted in transit (TLS 1.3) and at rest (AES-256), hosted in the EU, accessible only to the assigned engineer and deleted at the end of the engagement or on request.
Do you work outside Europe?
Yes. The platform is available worldwide and our engineers handle cases remotely in English, French, Spanish and Russian, with on-site interventions on request.
