SL Green Realty has signed a long-term lease with Palo Alto Networks, covering an entire tower floor at One Madison Ave. The deal brings SL Green's 2023 signed office leasing volume to 491,913 square feet, while the REIT's office leasing pipeline has increased to over 1.0 million square feet, up from a 700,000 square feet pipeline just three weeks ago.
