NetExplorer provides a secure platform for file sharing and online collaboration, employing strong authentication methods, intrusion detection, and anti-theft measures to protect user data. Its infrastructure adheres to high security standards, including ISO 27001 and PCI DSS certifications, and features advanced data encryption, traceability, and real-time data replication across multiple storage clusters. The platform ensures that all stored data is protected and confidential, governed by French law, with a commitment to maintaining high levels of availability and integrity.

2. APPLICATION SECURITY
Your 100% secure NetExplorer platform

3. To secure the authentication process,
you can require users to enter a code
that is unique to them, in addition to
their password (OTP, SMS or Yubikey
token). Authentication is then
qualified as 'strong' because it
requires the concatenation of two
authentication factors.
Authentication by
username and password
NetExplorer users log in using the
assigned username and password
chosen. Passwords are never stored
unencrypted; they are "hashed and
salted" to protect their
confidentiality.

Detection of intrusion
attempts
NetExplorer includes an intrusion
detection system and can identify too
many login attempts on a user
account or from an IP address. When
an intrusion attempt is detected, the
attacker's login and IP address are
banned. The number of pre-ban
attempts and the ban time are
configurable by the administrator.
Anti-theft protection
of sessions
In order to avoid session hijacking and
identity theft through Cross-Site
Request Forgery (CSRF) exploits, the
NetExplorer platform doesn't send
any session cookies to the connected
customer, as is the case with standard
applications. NetExplorer uses a single
token that is sent unidirectionally and
not automatically.Access strategy
NetExplorer features access policies
by user group or account. It is
therefore possible to block certain
methods of access, to limit login
locations (IP address), and to
determine the time slots and days of
connection.

4.  NetExplorer has a virus scanner and a ransomware detection system.
 Each file deposited on the platform is analysed, regardless of the access method. Items added by
outside contributors via deposit links are also inspected. The anti-virus used is ClamAV. If the file is
corrupted by a virus, it will be rejected by the platform. Similarly, if the ransomware detection system
detects an infection, the user's account is blocked to prevent the spread of ransomware.
 All data exchanged with NetExplorer is encrypted using SSL and a 2048-bit
key.
 All NetExplorer access methods use HTTPS on port 443, providing maximum
security.
 The SSL certificate implementation method applied by NetExplorer provides
strong security guarantees. It has been given grade A+ which is the
maximum grade. This assessment is made by Qualys SSL.
Antiviral and anti-malware protection
Encryption
Password security
 The password security policy is based on the combination of three parameters:
- Minimum password length, in number of characters
- Rejection of passwords used too often (from the list of the 10,000 most frequently used passwords,
and therefore tested first in the event of attack)
- Password complexity index
Password Complexity for the user Security level NetExplorer complexity
index
1gZ6f4HsG Impossible to remember Medium (only 39 days needed to decode it) 25
We are NetExplorer Very simple Very high (1042 years needed to decode it) 35

5. Traceability
 NetExplorer ensures full traceability of all actions performed by users: login, adding a file, modifying a folder,
deleting a document, etc.
 All the actions are grouped together in event logs, allowing a filter and an accurate search of the various
operations. Search by:
- Keyword
- User concerned
- IP address of the user
- Date of the event (beginning and end)
- Event status: success or error
- Object type: user, folder, file, annotation, etc.
- Type of action: login, addition, modification, deletion, download, etc.
 This traceability makes it possible to check and control the actions carried out on the platform, and to provide
evidence in case of dispute.
 As part of the PCI DSS certification, the NetExplorer application has successfully passed the 54,000 intrusion
tests performed by the Nessus app. These tests verify the absence of application security vulnerabilities,
such as SQL injections, XSS vulnerabilities, etc.
 For more details: http://www.tenable.com/solutions/pci-dss.
 Before every release or upgrade, NetExplorer undergoes more than 5,000 unit tests to check for bugs and
security breaches.

6. INFRASTRUCTURE SECURITY
Highly secure French storage

7. Data centres
 NetExplorer servers are located in France and
more specifically in Paris. All the data stored is
therefore governed by French law and is not
subject to the American Patriot Act.
 Our infrastructure operates two Data Centres
classified Tier 3+ and Tier 4: Zayo and Equinix
(ISO 9001 and ISO 27001 certified). Tier 4 (the
highest classification) provides an availability
rate of over 99.995%.
Private cloud
 All NetExplorer platforms are architected in
a private cloud to guarantee an excellent
level of confidentiality. The stored data is
completely partitioned in independent areas
between customers. A NetExplorer instance
includes a customer-specific database and a
dedicated storage system.
• The database contains all the platform information
(user accounts, groups, etc.), the stored content
tree menu, and the metadata. It ensures
consistency of information and controls security for
data access.
• The NetExplorer storage system only backs up the
file's binary data in an arbitrary format that is
completely independent from the actual document
tree. In addition, the document name and its
extension are obfuscated.

8. Availability and integrity of data
 Data availability: to ensure a very high level of availability and not be vulnerable to hardware failures, the
storage system provides local and remote information redundancy.
 Data integrity: the NetExplorer storage system calculates integrity every time a file is deposited. During file
transfers, a second integrity check is performed to ensure that the stored data is identical to the initial data,
and that it has not been altered during the transport of the information.
Data replication policy (backup)
Replication of files in real time
At NetExplorer, data is replicated in real time
across three different storage clusters. The first
two are located in the main data centre, and
the final server is in a second data centre,
located 30 km away. As such, in the event of a
major incident in one data centre, the data is
always stored securely in the second.
Data retention
All deleted files are kept for 30 days in the
backup logs. It is possible to restore a file or the
entire platform from up to 30 days back, even if
the document was inadvertently deleted.
