As digitalization and automation progress, so do the risks for industrial companies. Every new connection, every additional system and every interface can be a gateway for cyber attacks. Production downtime, security incidents and reputational damage are therefore among the greatest threats to critical infrastructures and manufacturing companies. <\/p>\n

The IEC 62443<\/strong> series of standards provides an internationally recognized framework for managing these risks in a targeted manner. It combines technical measures with organizational processes and thus creates the basis for greater security, resilience and trust<\/strong>. Companies that rely on IEC 62443 not only protect their systems, but also their future capabilities in global competition. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

It describes how manufacturers, system integrators and operators can jointly develop and operate secure products, systems and processes. <\/p>\n
The parts of the standard interlock seamlessly: manufacturers develop safe components (IEC 62443-4-1 & 4-2), integrators use them to build secure comprehensive systems (IEC 62443-3-3), service & maintenance providers ensure secure commissioning (IEC 62443-2-4) and operators safeguard ongoing operations organizationally (IEC 62443-2-1). Each role has its place in the security strategy. Only through the interaction of all standard parts can a thorough security concept be created for your products or systems. <\/section>\n[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row type=”full_width_background” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” bg_color=”#ffffff” scene_position=”center” top_padding=”6%” bottom_padding=”6%” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” row_position_desktop=”default” row_position_tablet=”inherit” row_position_phone=”inherit” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” shape_type=””][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” enable_animation=”true” animation=”fade-in-from-bottom” animation_easing=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” content_layout=”default” gradient_type=”default”][tabbed_section style=”vertical_modern” tab_color=”Extra-Color-1″ vs_content_animation=”fade” vs_link_animation=”opacity” vs_navigation_alignment=”left” vs_navigation_width_2=”25%” vs_navigation_func=”default” vs_navigation_width=”regular” vs_navigation_spacing=”25px” vs_navigation_mobile_display=”visible” vs_tab_spacing=”40%”][tab icon_family=”none” title=”General” id=”1773395314847-6″ sub_desc=”IEC 62443-1″ tab_id=”1773395314848-5″][vc_row_inner column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” text_align=”left” row_position=”default” row_position_tablet=”inherit” row_position_phone=”inherit” overflow=”visible” pointer_events=”all”][vc_column_inner column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” flex_gap_desktop=”10px” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” overflow=”visible” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][vc_column_text css=”” text_direction=”default”]\n
