Cybersecurity services

Neglecting cybersecurity means exposing yourself to major risks.

Cyberattacks are becoming more frequent and more sophisticated. Intrusion, hacking, phishing, CEO fraud, ransomware... no business is immune. According to an Asterès study, the average cost of a successful cyberattack in France is €58,600 and can threaten a company's survival. Cybercrime is a real threat; cybersecurity is the best defense. De Shagan Network offers a range of effective, tailored and scalable services.

SMEs: simple cybersecurity solutions

SMEs often think that a simple antivirus and firewall are enough to protect them. They also wrongly believe that hackers are not interested in them because they do not handle as much data as large companies. Wrong. It is not only castles that get burgled. Cybercriminals know that SMEs are often less protected than large companies, and therefore easier to attack.

According to the same Asterès study, in 2022, 52% of SMEs and 42% of micro-businesses were victims of a cyberattack.

Most common attacks against SMEs

Automated ransomware : malware encrypts company files or blocks access to computers, then demands a ransom to unlock them. This cyberattack can paralyse the business.
Mass phishing : credential theft and propagation of attacks.
DDoS attacks on e-commerce sites and SaaS services : blocking of online activity.
Identity fraud : fraudulent invoices, misappropriation of funds.
Fake job offer scams (Job Scam) : fake recruitment to steal HR data.

De Shagan Network offers tailored support with:

awareness of security issues;
advanced protection with firewall, EDR and anti-ransomware solutions;
access security and multi-factor authentication (MFA);
simple tools and hands-on support;
continuous monitoring and incident response;
a single point of contact and 24/7 assistance.

Mid-caps: cybersecurity as a business asset

Mid-sized companies (ETI) represent significant economic weight, but their cyber protection resources are often less effective than those deployed by large groups. ETIs are therefore a prime target for cybercriminals. A cyberattack can come from outside the company, but also from within.

De Shagan Network offers cybersecurity that is quickly operational and easy to adopt.

Most common attacks against mid-caps

Classic ransomware (LockBit, Ryuk, Conti, REvil, Cl0p, etc.) : data encryption followed by a ransom demand.
Advanced phishing attacks (Spear Phishing, Vishing, Smishing) : credential theft and access to information systems.
Remote access attacks (VPN, RDP, Citrix, Shadow IT) : brute-force or exploitation of vulnerabilities on remote access.
SaaS and cloud compromise (Office 365, GSuite, AWS, Azure, etc.) : exploited misconfigured security settings.
Online fraud (fake suppliers, wire transfer fraud) : cybercriminals impersonate a supplier.
Attacks via employees (Rogue Employee, internal malice) : theft or destruction of data.

De Shagan Network offers mid-caps tailored services:

network and critical access security;
advanced protection against ransomware and internal attacks;
Zero Trust solutions and network segmentation;
audit and compliance with regulations (NIS2, GDPR, ISO 27001);
long-term support with a dedicated contact;
scalable solutions adapted to your industry.

Large enterprises: cybersecurity is not optional

Large enterprises are targeted by cybercriminals for the financial resources they represent. With the development of AI, cybercrime is becoming increasingly sophisticated, cyber threats are multiplying and financial losses are growing heavier.

APT attacks (Advanced Persistent Threats) : cyber-espionage, long-term compromise.
Targeted ransomware (Ransomware-as-a-Service, double extortion) : against critical infrastructure.
Supply chain attacks : compromising a supplier to reach the company.
Zero-day vulnerability exploitation : cybercriminals or nation-states seeking previously unknown flaws.
CEO fraud / BEC (Business Email Compromise) : social engineering to fraudulently transfer funds.
Mass data exfiltration (Data Breach) : theft of customer or strategic data.

Depending on the sector, large enterprises must meet certain criteria, particularly in cybersecurity.

De Shagan Network offers large enterprises a full range of services:

evaluation audits;
audit and compliance with regulatory standards by sector (banking, healthcare, military, etc.);
security by design (risk management from the construction phase);
SOC deployment and managed services for continuous monitoring;
advanced training and awareness for technical teams;
dedicated ad hoc team setup.
