How Nexo’s Safety Works
Safety in crypto is a shared accountability. Platforms put measures in place — infrastructure controls, fraud detection, encryption — however a good portion of account threat might come from the consumer facet: weak passwords, unverified hyperlinks, addresses that get swapped with out anybody noticing.
This text covers each halves. What Nexo runs within the background, what unbiased auditors confirm, and what you possibly can allow your self to make your account meaningfully more durable to compromise.
What runs within the background
These function by default. There's nothing to arrange or allow — they're on for each account, each transaction.
Anti-scam engine
Each withdrawal on Nexo passes by an automatic anti-scam engine that analyses transactions in actual time earlier than funds depart the platform. If one thing seems to be off — an deal with related to recognized rip-off exercise, an uncommon transaction sample, a vacation spot that does not match prior habits — you may see a plain-language immediate explaining the priority. No jargon, no imprecise warnings. In uncommon high-risk instances, a transaction could also be briefly paused for overview.
The engine runs silently within the background. Most customers won't ever encounter it. That is the purpose.
Encryption
Information in transit and at relaxation throughout the platform is protected with AES 256-bit SSL encryption — the identical customary utilized by monetary establishments and large-scale cloud infrastructure globally.
Unbiased audits
Nexo's infrastructure is independently audited towards a stack of internationally acknowledged safety frameworks, all renewed yearly:
SOC 2 Sort 2 — operational safety controls and processes
SOC 3 — public-facing abstract of the SOC 2 audit
ISO 27001 — data safety administration
ISO 27017 — cloud-specific safety controls
ISO 27018 — safety of personally identifiable data within the cloud
CSA STAR Stage 1 — cloud safety assurance
They're carried out by unbiased third events on a recurring foundation.
What you possibly can allow
The platform facet covers infrastructure and transactions. What it could't cowl is your account entry — that depends upon how you have set issues up. These options can be found to each consumer and take minutes to configure.
Two-factor authentication (2FA)
2FA provides a second verification step at login. On Nexo, the identical verification — SMS, electronic mail, or authenticator app — can also be required at delicate actions: withdrawals, Tackle E book edits, and adjustments to safety settings. So even when somebody has your password, they can not transfer funds or change your setup with out the second issue.
Authenticator apps (like Google Authenticator or Authy) are stronger than SMS-based 2FA. SMS is weak to SIM swap assaults, the place an attacker convinces your cell provider to switch your quantity to a SIM they management. For those who're utilizing SMS 2FA, switching to an authenticator app is definitely worth the two minutes it takes.
To allow: go to your Safety settings and choose your most well-liked 2FA technique.

To set it: open the Nexo app → faucet your profile → Safety & Settings → Anti-phishing code → enter a code of your selection.
As soon as set, deal with any Nexo electronic mail with out your code as suspicious — no matter how convincing it seems to be.
Tackle whitelisting
One of many quieter assault vectors in crypto is deal with swapping — malware that silently replaces a copied withdrawal deal with with one managed by an attacker. For those who're not verifying the total deal with character by character earlier than confirming, it's possible you'll not discover.
Tackle whitelisting locks your withdrawals to addresses saved in your Tackle E book (as much as 500). You may also set an Additional Safety delay on newly added addresses — a configurable window earlier than a brand new deal with turns into usable for withdrawals. This closes the swap window: even when an attacker positive factors short-term entry to your account, they can not instantly withdraw to a brand new deal with.
To allow: go to your Safety settings and activate Tackle Whitelisting.
Channel validator
Earlier than interacting with any electronic mail deal with, social media deal with, or URL that claims to be Nexo, you possibly can confirm it at nexo.com/channel-validator. If it isn't within the validator, it isn't an official Nexo channel.
That is significantly helpful for social media — pretend Nexo accounts on X, Telegram, and Discord are widespread, and so they sometimes impersonate assist workers or run pretend promotion campaigns.
What Nexo won't ever do
Just a few issues price realizing, as a result of realizing them makes social engineering makes an attempt simpler to identify:
Nexo won't ever ask to your password or 2FA code
Nexo won't ever ask you to authorize a transaction by chat, electronic mail, or textual content
Nexo won't ever ship you a login hyperlink through SMS
If anybody claiming to be from Nexo does any of these issues, it is not Nexo. You'll be able to report suspicious exercise to the Consumer Care workforce at support.nexo.com/contact.
The place your account safety really comes from
No platform can remove all threat. What the measures above do — each the platform-side infrastructure and the user-side options — is cut back the assault floor and make your account considerably more durable to compromise.
The infrastructure handles what customers cannot see or management. The user-side options deal with what the platform cannot — as a result of no quantity of backend safety stops an attacker who has your credentials, or a consumer who clicks a phishing hyperlink.
Establishing 2FA through an authenticator app, enabling the anti-phishing code, and turning on deal with whitelisting takes below ten minutes. It is the highest-return safety motion most customers have not taken but.
