Defence in depth
No single barrier holds against a determined attacker. We connect identity, network, endpoint, email and data protection so that a control which is bypassed is followed by another one behind it.
Cybersecurity
LGC SARL secures the information systems of demanding organisations in Congo-Brazzaville, Switzerland and France. Security audits, monitoring, MFA, firewalls, EDR/XDR, vulnerability management, backup and disaster recovery planning: we build consistent layers of protection rather than relying on a single product, so your business keeps running even when an incident occurs.
No single barrier holds against a determined attacker. We connect identity, network, endpoint, email and data protection so that a control which is bypassed is followed by another one behind it.
Security is not only about prevention: it must allow you to restart. Tested backups, immutable copies and a written recovery plan give you a clear way back after ransomware or a major outage.
Banking, insurance, public sector, energy: regulated organisations must be able to prove what they do. We document configurations, log access and produce the evidence expected during an inspection.
Our base in Congo-Brazzaville and partner network in Switzerland and France facilitate on-site intervention, an understanding of local constraints and access to a contact person who speaks your language.
The starting point of any serious programme: understanding what you own, what is exposed and what would hurt most if compromised.
Early detection reduces the cost of an incident. We centralise signals and turn log noise into alerts your team can act on.
Most intrusions go through a legitimate account. Strengthening authentication and controlling privileges offers the best protection for the effort involved.
The perimeter and the endpoint remain concrete lines of defence, provided they are configured, segmented and kept up to date.
Finding your weaknesses before someone else does, then tracking their correction over time rather than in a one-off report.
A backup that has never been restored is only an assumption. We build and test the ability to bring your critical systems back.
We audit the existing setup, map the assets and identify the scenarios that genuinely threaten your activity. The output is a factual picture, without unnecessary jargon.
We propose a layered security architecture, ranked by risk and by the resources available to you. Every measure is justified by the threat it reduces and the effort it requires.
Implementation in batches to limit impact on production: identity and MFA, network and endpoint protection, backup, then monitoring. Configurations and procedures are documented as we go.
Continuous monitoring, alert review, vulnerability follow-up and periodic restore tests. What each incident teaches us feeds into the next cycle.
With an audit. Investing in tools before knowing what you protect and what is exposed rarely pays off. The audit produces a map and a remediation plan ranked by impact, so you can address the small number of items that matter most first.
A one-hour discussion is often enough to spot the most critical gaps: unprotected administrative accounts, needlessly exposed services, backups that have never been restored. Contact LGC SARL to arrange a security audit suited to your organisation.
