Why EV charging cybersecurity is now a business priority

EV charging networks now qualify as critical infrastructure in many markets - connected to the grid, processing payments, and storing personal data at scale. That makes them an attractive target.

Operators face threats across multiple layers:

• Credential stuffing and bot attacks targeting driver login and registration portals
• Ransomware and remote access exploits aimed at Charging Station Management Systems
• Protocol vulnerabilities in OCPP 1.6 deployments that lack modern security profiles
• Data breaches exposing driver payment information and personal data
• QR code phishing attacks placed on physical charge points

For CPOs and EMSPs, the consequences go beyond data loss. A compromised platform can take an entire network offline, trigger regulatory exposure under NIS2, and erode driver trust at scale. EV charging cybersecurity compliance is increasingly a procurement requirement - not a checkbox addressed after go-live.

What platform security means for EV charging networks

Most cybersecurity discussion in this space stops at the charger: OCPP encryption, firmware updates, and network segmentation. All necessary, but incomplete. The platform layer is equally exposed and frequently overlooked.

Driver portals, EMSP backends, API endpoints, and authentication flows handle millions of interactions and represent a wide, underprotected attack surface.

For operators running networks at scale, securing the platform means addressing:

• Authentication hardening: protecting login, registration, and password recovery flows against automated abuse
• Bot and fraud prevention: blocking non-human traffic that inflates session data, enables fraudulent charging, or degrades platform performance
• Compliance alignment: meeting the requirements of ISO 27001, SOC 2 Type II, and OCPP 2.0.1 security profiles across the full system

Ad-hoc charging flows (where drivers start sessions without registering) represent a particular exposure point. This is where Ocean's integration of reCAPTCHA directly addresses the gap.

How it works in practice

reCAPTCHA is deployed in Ocean's Ad-Hoc Driver Portal - the no-registration charging flow where drivers initiate sessions without a platform account. Because ad-hoc charging requires no login, it is an open entry point for fraudulent session initiation. Before any session is authorised, reCAPTCHA runs an automated risk assessment in the background, assigning each interaction a confidence score between 0.0 and 1.0. Requests that fall below the configured threshold are blocked before the session starts. Legitimate drivers experience no interruption, since the validation runs silently.

For CPOs, the protection is configurable directly from the operator portal. Operators can enable or disable reCAPTCHA, set the score threshold to match their risk tolerance, and configure the required service account credentials. Higher thresholds apply stricter validation - catching more suspicious requests, with a tighter margin for edge cases.

What this means for your network's security posture

EV charging cybersecurity is moving from best practice to baseline requirement. Networks that can demonstrate auditable security controls, certified platform architecture, and built-in abuse prevention are better positioned to win enterprise CPO contracts, satisfy regulatory obligations, and maintain driver confidence at scale.

For Ocean's partners, this translates into:

• Built-in reCAPTCHA protection for the Ad-Hoc Driver Portal - configurable by operators from day one, with no additional development required
• A platform architecture aligned with ISO 27001, SOC 2 Type II, and OCPP 2.0.1 security profiles
• Reduced exposure to fraudulent session initiation, credential abuse, and session manipulation across the full network
