Driven by exponential growth in the number of consumer IoT devices shipped to global markets, assuring the security of these devices is vital. Reports of vulnerabilities are common, be they for hacked IP cameras allowing hackers to spy into private households, or devices being captured by hackers and implemented into botnets. Baseline security requirements for consumer IoT devices have been defined and issued in standards by numerous organizations, but so far, they have been inadequately implemented in products. Recent regulations, such as the EU Cybersecurity Act, the GDPR, the California Consumer Privacy Act and state bills across the US are putting pressure on manufacturers and retailers to act. SGS Cybersecurity Services help you to manage and mitigate the risks. Governments, stakeholders and regulators across all industries around the world are working on standards and regulations to tackle the cybersecurity challenge with a focus on the complete supply chain, life cycle of components, products, networks and systems. Our service portfolio is tailored to address this situation holistically, helping our customers to raise their security maturity to the level required to meet the cybersecurity challenge through three services pillars offered as general services (independent of the sector) and tailored to a range of industries: TrainingAssessmentCertification  Build trust in your product and systems with SGS security evaluation against recognized cybersecurity standards.
