FAQ

Frequently asked questions

A penetration test simulates a real attack on your system — computer, website, application or network — to find vulnerabilities before a real attacker does. Everything is done remotely, with your authorization. You receive a full report with the vulnerabilities found and a concrete action plan.
We check if your information (emails, passwords, SIN, banking data) has been compromised and is for sale on the dark web. If data is found, we guide you step by step to secure your accounts and limit the damage before a fraudster uses it.
Contact us immediately. We intervene urgently to isolate the threat, clean malicious code, identify how the attacker got in, fix the vulnerability, and secure your site so it doesn't happen again. Typical response time: under 24h.
At a large firm, you talk to a salesperson, the work is delegated to a junior, and you receive a standardized report. At SEQUR: direct access to specialists, real technical expertise, custom report, fair pricing. No agency overhead, no useless jargon.
DApps & Web3: we design and deploy secure decentralized applications — architecture, wallet integration, private key management, on-chain protocols (Ethereum, Solana). Post-quantum: quantum computers will soon break RSA and ECC. We assess your systems and plan migration to NIST-resistant standards.
No. We operate remotely across Canada — Quebec, Ontario, British Columbia and beyond. All our services are offered online: audit, monitoring, forensics and consulting. If a physical intervention is required, we travel based on the nature of the request.
